Compact pulsed laser sources based on a heterothyristor current switch-laser diode assembly have been developed and investigated. These sources emit at a wavelength of 940 nm. It is shown that the use of heterothyristor current switches with an extended base makes it possible to increase the operating voltage up to 100 V without sacrificing the speed of transient processes. As a result, the possibility of generating laser pulses 1 ns in duration and peak power of 50 W has been demonstrated. Keywords: thyristor, current switch, laser pulses, heterothyristor.
