II-VI Laser Enterprise expands seed laser portfolio for pulsed fiber lasers

ZURICH, SWITZERLAND: II-VI Laser Enterprise GmbH, a subsidiary of II-VI Inc. and a global leader in semiconductor lasers, will debut new products from its expanded Seed Laser portfolio at Photonics West 2014.

These include a new Fabry Perot (FP) laser diode module with ultra-broad band fiber Bragg grating (FBG) for high peak power pulsed Fiber Lasers and a Distributed Feedback (DFB) laser diode module designed for seeding of sub-nanosecond Fiber and Solid State lasers.

The expanded Seed Laser portfolio comprehensively addresses all pulsed fiber laser applications and includes:

* An innovative DFB single-mode laser diode with an on-chip distributed feedback grating that enables pulsed Fiber Lasers to operate at picosecond pulse widths as well as enables frequency conversion into
green and UV wavelength ranges. Available at 1064 nm and 1030 nm, the Seed Laser is capable of high peak powers of up to 800 mW for a pulse width as short as 150 ps tunable up to 4ns with programmable pulse shapes and a spectral line-width well below 100 pm.

* A FP Seed Laser module with a 4nm ultra-broad band chirped FBG, tailored to control spectral properties for the suppression of SBS (Stimulated Brillouin Scattering), a common problem in pulsed fiber lasers that occurs above 10 ns pulse width and at high peak power operation of pulsed fiber lasers. Available at 1064nm, the module can be operated at peak currents of up to 2 A.

* A narrow-band FBG FP laser module for pulsed frequency conversion applications. The laser module with less than 0.3 nm bandwidth and FBG at a short distance is available at 1064nm and 1030nm.
