Multiwave diode pumped Q-switch ErYLF-laser

The results of theoretical and experimental investigations of spectral and power parameters of diode pumped multiwave Q-switch Er:YLF-laser are presented. The series of giant pulses on 2.66, 2.71, 2.81um wavelengths at peak power up to 100kW and pulse duration 30ns were obtained. The theoretical optimization of laser resonator to improve of laser radiation brightness and beam quality was carried out.
