IPG Photonics announced the successful test of its new ten kilowatt single-mode fiber laser, a world record in an industry laser. The unique laser produces 10.1 kilowatts of single-mode power through a single fiber at total efficiency exceeding 23%. IPG’s new kilowatt laser has multiple applications including remote cutting and welding as well as directed energy.

Representing the latest development in the power scaling of IPG Photonics’ patented high-power single-mode fiber laser technology, the laser’s optical scheme consists of a fully-integrated MOPA (master oscillator power amplifier) with an output delivery fiber 1.5 meters long directly spliced into the booster amplifier. The Company’s ten kilowatt single-mode laser, the YLS-10000-SM, is the world’s brightest industrial CW solid state laser given the combination of output power and virtually perfect Gaussian beam-quality at 1070 nm emission wavelength. Developed by its subsidiary IPG Laser GmbH, the YLS-10000-SM is a turn-key package that offers a small footprint and record efficiency wall-plug.

“The ten kilowatt fiber laser builds on our prior success with the five kilowatt single-mode lasers we introduced last year” stated Dr. Valentin Gapontsev, Chief Executive Officer of IPG Photonics and an inventor of the new laser. “We designed a new state-of-the-art power amplifier to overcome thermal limitations, avoid higher order modes and non-linear effects, despite the enormous power density at this output level” he added.

“Industrial customers can now use fiber lasers for applications which were not previously possible with other lasers, such as remote cutting and welding without expensive assist gases in the infrastructure, automotive, aerospace and shipbuilding industries” said Bill Shiner, Vice President of Industrial Markets. “Mobile applications such as bridge construction and repair and ship and airplane paint removal can now take advantage of higher output powers in a mobile and robust laser package to increase the distance to the work piece.”

This industrial product also has applications in tactical directed energy markets. The combination of ten kilowatts of output power with near-perfect beam quality and the inherent reliability, efficiency and ruggedness of a fiber laser in a compact package is a compelling solution for a variety of tactical directed energy applications.

IPG Photonics’ Laser Survives High Speed Highway Crash

IPG lasers are known for their durability and ruggedness and have survived months of service in theatre in HumVee’s and one high power unit recently survived a high speed highway crash! Figures 1 & 2 show an IPG fiber laser after suffering a highway accident in which the trailer carrying the laser flipped and the laser hit the highway (inside a Conex) on its side at approximately 60 mph. Although the laser frame and power supplies were ruined by the impact, all 34 M66 optical modules survived the crash and have been successfully tested at full power meeting all specifications (Figure 3). Thankfully, no one was seriously injured in the crash.

Ablation Characteristics of Silicon for 532 nm Fiber Laser

The fabrication of advanced solar cells with high conversion efficiency frequently requires technologies such as back contact formation, buried emitters or edge isolation. These processes are best performed by the application of laser technology in one form or another. The issue then becomes the selection of an appropriate laser that best performs a given process. This is often determined by extensive testing of lasers with various laser characteristics since the performance and materials interaction of a given laser are not generally established. IPG has characterized the performance of certain lasers for the PV industry. Work has been performed to establish the removal rate of Si by pulsed lasers operating at 1064 nm and 532 nm and under a variety of operating conditions such as peak power, average power, scanning speed and number of scans. The data enables engineers to determine the relevant laser parameters for a given target process with a reduced requirement for testing.

IPG Photonics Corporation announced the availability of government programs that provide financial incentives for customers to purchase fiber lasers. Fiber lasers, which are vastly more energy efficient than conventional YAG and CO2 gas lasers, are well suited for the new financial assistance programs which promote the deployment of energy efficient technologies.

One such program is the Clean Energy and Industrial Efficiency Program of the Massachusetts Department of Energy Resources (DOER). The DOER is reviewing applications for proven commercially available technologies with a minimum efficiency improvement of 25% into the industrial sector. The DOER program is based on the United States Department of Energy’s Funding Opportunity Announcement for $156 million in awards to deploy energy efficient technologies under the terms of the American Recovery and Reinvestment Act. There is no cap on the amount of funding per applicant.

Fiber lasers, a proven commercially available technology, convert electrical energy to optical energy 2 to 3 times more efficiently than diode-pumped YAG lasers, 3 times more efficiently than CO2 lasers and 15 to 30 times more efficiently than lamp-pumped YAG lasers. Because fiber lasers are much more energy-efficient and place lower levels of thermal stress on their internal components, they have substantially less electrical requirements than compared to conventional lasers.

In addition to government programs subsidizing the switch to energy-efficient fiber lasers, electric utilities provide incentives to purchase fiber lasers. Check with your local utility company as we have found most states offer rebate programs.

“Due to the high energy efficiency of our fiber lasers, one customer has already received 50% funding in Florida by switching to fiber lasers for its materials processing application” stated Bill Shiner, Vice President of Industrial Markets. “Sometimes the capital cost of new equipment is a roadblock for utilizing more efficient equipment like fiber lasers. With new incentives available from the government and utilities, customers can deploy IPG’s proven industrial lasers that provide great improvement in energy efficiency in addition to lower maintenance.”
