II-VI Laser Enterprise debuts 1.5W 1060nm seed laser

The Zurich, Switzerland-based II-VI Laser Enterprise GmbH subsidiary of engineered materials and optoelectronic component maker II-VI Inc of Saxonburg, PA, USA has unveiled a new generation of high-power 1060nm single-mode laser diode seed modules.

The new laser diode module is designed to seed nanosecond pulsed fiber lasers addressing the fast-growing market for MOPA (master oscillator power amplifier) fiber lasers. The module delivers kink-free power up to 1.5W in nanosecond pulse operations, enabling highly efficient pulse amplification and improved frequency conversion for optimal beam quality and throughput in fiber-laser systems.

"With 40% more pulse power compared to our previous offering, our new diode seed module enables the next generation fiber-laser systems for a wide range of applications," says Karlheinz Gulden, general manager, II-VI Laser Enterprise. "Together with our distributed feedback laser [DFB] diode module designed for sub-nanosecond operations, we offer customers the most comprehensive seed laser diode portfolio in the market," he claims. 

The new laser diode seed module features a higher-power 1060nm Fabry-Perot single-mode laser diode chip and a standard cooled telecom 10-pin mini butterfly-type package that includes a thermistor and back-facet monitor photodiode. The 75% smaller form factor of the mini butterfly package versus the legacy 14-pin version enables a reduction in overall footprint of the seed assembly. A broad- or narrow-band fiber Bragg grating [FBG] is optionally available to control the spectral properties for the suppression of stimulated Brillouin scattering (SBS) or for the improvement of frequency conversion performance, respectively.

II-VI Laser Enterprise is showcasing the new laser diode seed module in booth # 2223 (hall C) at SPIE Photonics West 2016 in San Francisco, CA (16-18 February).
