NEW Optical Feedback

The newly developed motor drive with the new active optical feedback allows an extremely precise wavelength control and stabilisation. The new active feedback allows moreover a fully automated wavelength calibration and an almost linear scanning. Active temperature control, online energy control and stabilisation, as well as online bandwidth control are further advantages of the new active optical feedback. Together with the new, completely revised motor drive and the new software, we achieved a precision with reproducibility of the laser-line, linear scan, wavelength control and autocalibration, which is, to our knowledge, not reached by any other laser worldwide.

Fine mechanics In the range of fine mechanics we optimised the adjustment of the deflecting prism for the oscillator and preamplifier by the use of a highly precise prism rotary table. Also our mirror mounts and beamsplitter mounts are further optimised. Software The new software allows to drive the motor back beyond the starting point of scanning measurement. This is done to determinate the absolute starting point of the measurement with highest precision.

CCD-Camera

The Camera has 1280 x 1024 pixel and the frame rate is more than 14 pictures per second. That is more than enough to control the laser bandwidth or to stabilize the wavelength against thermal shift. It is possible to set the repetition rate of the laser to synchronize the camera. The written software displays the rings of the etalon and the summed spectra of the rings. This information is necessary to calculate the bandwidth or to stabilize the laser. For more Information see software for pulsed dye laser.

Additional options

When designing this new series of NarrowScan dye lasers we paid utmost attention to a flexible layout, meeting a variety of applications with a dye laser. The following options can be easily integrated into the housing of the NarrowScan laser to guarantee a rigid and compact structure. Frequency doubling and -tripling, difference frequency mixing The excellent spectral and spatial quality of the NarrowScan-series predestinate this laser for the use in nonlinear processes. By means of our very precise positioning tables, all common crystals for frequency doubling and difference frequency mixing can be installed the housing of the NarrowScan-laser. By installing this positioning stage directly inside the laser housing, a high stability and reproducibility is achieved. For difference frequency mixing (up to 4,5 µm) the dye laser wavelength is mixed with one of the harmonics of the Nd:YAG-laser. The necessary opto-mechanical components for the pump laser beam are also located inside the laser housing. (see NarrowScan options)

Actively and passively stabilized Dye Ring Laser

Our new carefully designed and optimized single mode ring resonator guarantees – in any configuration - high performance, stability and easy operation. All optical elements, including the dye jet and titanium:sapphire are mounted on an extremely rigid 58 mm diameter Invar rod. This extremely rigid, high thermal mass structure reduces system sensitivity to vibration and temperature changes. In our laser system we adopted the concept of Coherent and improved some important features like handling, adjustability and costumer-friendliness. Our laser is characterized by very high stable, precise opto mechanical components and stable reproducability of the adjustment. Due to the fact that we use a hysteresis free Galvo drive instead of piezo drives, the laser is able to perform reproducable, narrowband wavelength scans. The laser is equipped with our RD 1000 CW dye circulator that is absolutely vibration-free and our special dye nozzle RDSN02 which is interferometricly tested and provides a vibration-free dye jet.

Standing wave Dye-Laser and Ti:Sa Laser

This dye laser is based on our exchange unit for the Coherent 699 ring laser RDU 10 (nozzle holder and pump mirror adjustment). We paid attention to it that the laser is easy to handle. By an adjustment with micrometer screws a very high reproducibility is guaranteed. The laser is mounted on a 50 mm invar rod and the dimensions allow a later installation of the etalon for single

mode operation. It consists of a 3-mirror-resonator, wavelength tuning is done by rotation of the Lyot-filter. The standard laser is equipped with a 0.2 mm low pressure nozzle in connection with our dye circulator RDN 2000 CW. An advantage is the simple laser dye change by a reproducible exchange of the complete nozzle holder with nozzle and dye circulator. The further advantages of the RD-cw-linear dye laser are:

• Compact and stable resonator configuration • Simple, fast and reproducible adjustment • Good efficiency

Accessories for cw Dye laser The following cw laser accessories should be used in order to achieve an absolutely steady and precise dye jet for Radiant Dyes, Coherent, Spectra Physics and for custom-made laser systems. We carry two different types of dye circulators and air cushions which were designed in such a way that vibrations due to the geared pumps can be avoided completely. This is achieved by a high efficient especially spooled cooling coil and also by the air buffer inside the stainless steel filter housing. As in all our other dye circulators we paid attention to the exclusive use of stainless steel and synthetic materials which are not harmful to the laser dyes and withstand high pressures. Our low pressure dye circulator is the most appropriate pump for all usual applications with standing wave and ring dye lasers. For all high stabilised applications we recommend the low pressure air cushion and the 0.2 mm special dye nozzle RDSN 02 (interferometrically tested). For all special applications where high pressure and flow rates are required we recommend the high power dye circulators and dye nozzles with different thicknesses.

RD 1000 CW High performance gear pump consisting of: 380 Volt motor with max. 2800 rpm, up to a maximum pressure of 7 bar, max. flow rate approx. 6 l/min., integrated aircushion in the filter housing, non-ferrous metal, only stainless steel and plastics that are resistant to all known solvents

Dye jet thickness 0.2 mm for original Coherent or Spectra Physics pumped dye systems. The nozzle can be used for pressures of approx. 12 bar, depending on high pump energies (20-25 W). So the nozzle covers almost all applications. On request, we also deliver dye nozzles with the thickness 0,05; 0,1; 0,3; 0,4; 0,5 and 1 mm.

Power Measuring Heads

The listed power heads are based on thermoelectric principles, which means that the heat generated by the incident radiation is transformed directly into a voltage.

The head of BB–series has a black, broadband absorbing coating. The HP–series are equipped with a ceramic coating which allows high energy and power densities.

The head HP 25 S is specially made for service. The compact dimensions enable easier transport. Due to the smaller heat sink, high powers are only possible for a short time.

The heads need some seconds to reach a thermal equilibrium. To avoid this delay time, we recommend the use of one of our power meters, such as LEM 2420. These devices determine the voltage and its increase and evaluate the laser power from this data. The time constant from the whole system is reduced to 1 second.

Raman Cells Raman shifters are suitable for a frequency conversion of fixed or tuneable laser sources and for the suppression of amplified spontaneous emission (ASE) and are based on stimulated Raman-scattering (SRS). The most commonly used gases for this purpose are H2, D2, O2 and N2. SRS is a flexible, economic and easy to handle wavelength extension method. In addition, tuneable radiation down to 150 nm can be generated if the pump (dye laser) radiation provides sufficient high energy (= 30 mJ) and good focusability. Starting in the visible or ultraviolet with tunable dye laser radiation, the complete spectral interval down to 150 nm is accessible without gaps by using different dyes. The conversion efficiencies are more than 20% for the first Stokes and around 5% for the first anti-Stokes component. The efficiencies for higher order anti-Stokes components scale approximately with: ASn+1 ~ ASn x 0.3 for n > 1 Continuous tuneable radiation from 190 nm (anti-Stokes generation) up to the far infrared region (Stokes generation) can be generated by using one Raman cell and one non-linear medium (e.g. H2). Vacuum-flanges to connect the Raman cell to a vacuum vessel can be ordered from Radiant Dyes. RD-RS RAMAN-Shifter Construction kit The Set contains: Cylindrical stainless steel gas pressure cell (approx. 1.20 m) with end flanges. A positive quartz lens is used as entrance window, a quartz plate as output window. The set contains also: A quartz collimating lens, one input (gas-in) and one output (to vacuum pump) valve, one pressure gauge (0 - 40 bar), one adjustable pressure relief valve adjusted to max. 40 bar and mounting equipment to fasten the cell upon an optical table. All components are made of stainless steel. All connections are standard Swagelok parts. The Raman-cells are pressure tested by Radiant Dyes. This and the automatic pressure relief valve minimises potential hazards. The RAMAN-Cell must be installed in an explosion proofed housing. We take on no responsibility for accidents because of improper use.

Pyroelectric Energy Detectors

The detectors of the PEM series are suitable for measuring laser pulses in the range of some Mikrojoule up to several Joule and they cover the whole spectral range from the UV to the far IR. The PEMs do not need any external power source, because they work with the pyroelectric principle. At the output of each detector the voltage signal is measured off, with the amplitude proportional to the irradiated laser energy and determined by a calibration constant, which is ascertained for each PEM by the manufacturer. Each detector is equipped with standard BNC-plugs.

The PEM 10 is especially designed for measuring small laser energies in the range of Micro- and Millijoule. The special coating of the active sensor diameter allows a broadband sensitivity of 0.19-10 mm. Because of short signal rise and drop times measurements with repetition rates up to 300 Hz are possible. Higher repetition rates up to 500 Hz on request! The PEM 25 has the same special broadband coating as the PEM 10, but with a larger active sensor diameter (∅25 mm). The outstanding feature of the PEM 48 is its high detector aperture of ∅48 mm for the easy pulse energy measurement when working with an excimer laser. The PEM 8 HP is especially designed for lasers with low pulse energies and high energy densities at the same time (like dye and small Q-switched Nd:YAG-lasers). The damage threshold lies above 2 J/cm² with pulse widths of 5 ns at 1064 nm. The PEM 20 HP is well suitable for high pulse energies (up to 6 J) and high energy densities at the same time (2 J/cm²), occurring with Q-switched Nd:YAG-lasers. Cooling fins at the housing allow capacities up to 60 Watt PEM 10 PEM 25 PEM 48 PEM 8 HP PEM 20 HP PEM 48 HP

Pyroelectric Energy Detector PEM 50K with black ceramic absorption sheet for extremely high energies The PEM 45K is a further developed PEM 50M, which is even more resistant against radiation through its ceramic absorption coating. Energy measuring chip EMS 1.6 Technical data: Detector sensitivity: 0.01 - 2000 V/J Trigger level range: 0 .... 99,9% Correction factor: 0 .... 99,9% Type of measurement:

• Pulse energy with measuring range 20 mJ, 200 mJ, 2 J, 20 J and automatic range. • Measuring of the mean with the choice of the pulse number (2 to 1000) and auto-reset. • Pulse stability measuring „Peak to Peak“ • Measuring of the mean pulse stability

Statistical measurement for the choice of the pulse number: minimum, mean or maximum energy, standard deviation in %. Preamplifier for Pyroelectric Energy detectors VST1N/VST2N With these amplifiers it is possible to measure the smallest laser energies (some 100 nJ/ PEM 4). There is an extraordinary increase of the receiver as a result of the selected amplification and the omission of the capacity of the measurement head through the measurement wire. The bandwidth of the amplifier is especially designed for this application. The amplifying is fixed by Radiant Dyes and selected by the customer with the order. The type VST2N has the possibility to switch the amplification (two amplification factors). Through this modular type of construction the dynamic range of the measuring head is raised a lot. Also the losses of the sensitivity can be compensated by using a smaller resistance. Specifications:

• Plugs BNC • Amplifying 10-, 100-, or 1000-times

• Input resistance 1 MΩ • Length of the supply 3 m • Power unit (included) ± 15V

Neutral glass filter set RDNG 1-30 4 filters with transmission of approx. 1%, 5%, 10% and 30%. Maximum power density up to 100 MW/cm².

Laser dyes Since 1982 we synthesise laser dyes in excellent quality. The extensive quality management of our experienced chemists ensures a constant quality on a high level. Our offer consists of a broad range of laser dyes to cover all desired wavelengths. All special data are listed in the table of our dye poster, already mentioning the pumplaser which is used. We offer solvents in laser quality, which are the optimum solvents for Coumarine, Rhodamine and Cyanine dyes because of their high polarity. The high viscosity of Ethylene glycol shows to be an advantage for the use of cw-dye lasers.

Ready-to-use dye solutions

As a special service we offer ready-to-use dye solutions, which are made individual on customer request. But please note: we recommend to buy dye and solvent separately, because dyes have a better durability as a dry powder than a solution. Important advice: Take care, that your dye solution contains no solid particles before use. Often an ultrasonic bath helps to solve the dye. At a change of dye to another wavelength the dye circulator must be flushed with clean solvent. Otherwise the efficiency can be reduced or destroyed by dye rests. Please notice: Handle all dyes and solvents with care! A lot of dyes (also as solution!) are known as hazardous or irritating. The solvents can carry the dyes through the skin into your body (e.g. Benzyl alcohol, DMSO, Dioxan, Methanol) Always wear rubber gloves, protecting masks, goggles and clothes when weighing and solving the dyes. In case of skin contact wash with plenty of water! Please, make yourself clear, which solvents are combustible and take care to avoid any danger!

Excimer Laser

Compact Excimer Laser

RD-EXC-5 RD-EXC-20 RD-EXC-200 RD-EXC-300

The excimer lasers are small sized and low priced standard lasers with integrated power supply

and corona pre-ionization. Solid nickel electrodes are used near the gas discharge where the

halogens are most reactive. This provides a longer component lifetime and a better long-term

beam uniformity. The laser is equipped with an internal electrostatic window protection system

to increase the gas lifetime and the window cleaning intervals. In combination with our dye

lasers this laser opens a variety of applications in the field of spectroscopy and non-linear optics

where medium pulse energies and powers at repetition rates of up to 200 Hz are needed.

Heat Exchangers In laboratories with existing cold water circulators, our

standard heat exchangers are a good alternative for cooling

bigger systems; for example for the cooling of high power

excimer lasers, argon or krypton-ion-lasers as well as other

laboratory equipment. Our standard heat exchangers do not

have a temperature stabilisation.

The mentioned cooling powers are based on a flow rate of 20 l/min. and a water temperature of 12 °C on the secondary side. At different temperatures or different flow rates the cooling power changes accordingly. Besides our standard systems we are in a position to

manufacture cooling systems up to several 100 kW, according

to customer specifications.

Cooling power up to 7 kW, depending on the flow rate, pressure approx. 1.5 bar, 30 l coolant reservoir Dimensions: 565 x 365 x 595 mm³

RDW 25 Cooling power up to 25 kW, depending on the flow rate, pressure approx. 3.5 bar, 30 l coolant reservoir Dimensions: 565 x 365 x 595 mm³

RDW 45 Cooling power up to 25 kW, depending on the flow rate, pressure approx. 3.5 bar, 30 l coolant reservoir Dimensions: 565 x 365 x 595 mm³ Our standard heat exchangers do not have a temperature stabilisation.

9.2 Cooling Aggregates

Our cooling systems (water/air) and heat exchangers (water/water) are completely made of stainless steel and can be operated with anti-corrosive coolants which prevent a corrosion of

excimer lasers as well as a calcination of laser cooling circulators. Our cooling systems are available

between 0.5 - 6 kW. They are equipped with efficient recirculation pumps, which provide a flow rate

of 10 - 15 l/min in excimer lasers for example.

Our cooling systems RDK Maxi can be extended to a total of three cooling circulators by the use of two additional pumps. Thus a simultaneous cooling of up to three lasers or one laser and several dye circulators is possible with only one cooling system. The cooling systems RDK Midi can be equipped with one additional pump.

Our RDK systems are not designed for de-ionised water or other aggressive media, on request, they can also be supplied for these coolants.

Dimensions: 295 x 385 x 460 mm³ 565 x 365 x 595 mm³ 605 x 405 x665 mm³

All our cooling systems can also be equipped with water gauge and outside thermometer (Surcharge). All cooling

systems have a thermostat (approx. 8 - 18 °C) and a temperature stabilisation (± 2 °C).

Electronic temperature stabilization 1 °C optional

Radiant Dyes Thin Disk Laser

We have also realized a disc laser with a two beam output of 2x 10/14 W at 515nm allowing us to pump two dye/Ti:Sa laser simultaneously. Due to this two beam technology the stress on all optics has been reduced dramatically which leads to a long durability of all components. This 2x 10/14 W laser can be offered for a price only 20% more than a single beam laser with 10/14 W.
