The subject of this study was a laboratory model of a small microchip laser system, which consists of an emitter based on an Nd:YAG/Cr:YAG active crystal with passive Q-switching, a pumping system (i.e., a multiwave laser diode array consisting of five laser diode bars), a lens system for collimation and focusing pump radiation, and a power source for laser diodes. The aim of the work was to develop and examine a compact, portable microchip laser with high peak power and energy per pulse operating over a wide temperature range. Method. Owing to the use of a multiwavelength laser diode array as a pump source, the laser does not require complex thermal stabilization circuits.

The possibility of using the array of multiwavelength laser diodes as a pump source for the passive Q-switched microchip Nd:YAG laser based on a saturable Cr:YAG absorber is demonstrated. This pumping enables the use of the thermal stabilization system to be avoided under typical environmental conditions. The small microchip laser system (the volume is 1 dm3 together with the power supply of the pump laser diodes) was fabricated.
