Leaders in Light Perfect for Raman
Torsana Laser Technologies A/S
Founded 1996 100% owned by Juel Nielsen Holding A/S Based on a 50-year old tradition of consistent innovation
Perfect for Raman microscopy
Starbright technology advantages: Ultra high spectral and spatial
resolution enabled by excellent beam quality and line width
Very high sensitivity due to effective repression of ASE
Short acquisition time with high power
Flawless stability in wavelength and power
Claim ratio is less than 2 % on all end users since August 2005
Strong wavelength stability
Excellent spectral resolution enabled
Courtecy of Jasco
Tapered diode
Single mode diode with integrated amplifier structure
Enbles combined advantages of single mode diode reliability and life time, with the high output power ensured by the integrated amplifier
Impeccable quality performance
Claim ratio is less than 2 % on all end users
Since August 2005
Quality assurance
Carefully selected diode manufacturer, producing to our specifications.
Rigorous testing and selection of diodes.
Special cavity design and electronics ensures correct optical and electrical operating environment for the diode. This removes unwanted optical stress for the diode, which could have long term effects.
Quality assurance
Highest precision specification measurement report for each laser including simulation of room temperature change.
Strong destructive temperature cycling performed on each cavity to ensure long-term alignment stability.
300 hrs performance test on each laser before shipment.
Extensive testing procedures1. A-test Verifying specification fulfilment,
By monitoring stability of wavelength and power, plus single frequency operation, in changing external/ambient temperature conditions: 20-> 30-> 20.
2. Temperature stress cycling procdure with the diode turned off. Internal temperature of the laser is temperature is rapidly and strongly cycled up and down.
3. B-test Verifying long term alignment immobility of components. By ensuring performance is completely unchanged, after the temperature stress cycling procedure. Comparing test A and B.
4. Long term running, for 300 hours.
5. End test Verifying specification fulfilment again, The same way as the A-test.
6. Individual test report as above is shipped with each laser.
Example of A, B & End testing
