Abstract

The features of developing microchip lasers with passive Q-switching are considered. The active medium of the laser is an epitaxial layer of the saturable absorber Cr⁴⁺:YAG grown by liquid-phase epitaxy on an Nd:YAG substrate. Laser mirrors were deposited by electron-beam evaporation. Pumping was carried out with a continuous-wave semiconductor laser (808 nm). The obtained laser parameters are: pulse duration of 1.3 ns, pulse repetition rate of 5.5 kHz, and peak pulse power of 1.2 kW.
