Abstract

The results of research and development of a pulse laser module are presented. The aim was to create and a compact pulse laser source with a peak power of more than 10 W for optical pulses of 10 ns - 10 μs duration, emitting in spectral range 900-1600 nm. Pulsed modules were based on MOCVD-grown edge-emitting multimode semiconductor lasers integrated with a pulse pumping board. It was shown that the laser output characteristics can be optimized via a series resistance in the laser pump circuit. The 1550 nm wavelength modules with free-space outputs showed power levels of 15 and 25 W, for 1 μs and 100 ns pulses respectively, at 25° C temperature with a regular pulse shape.
