Abstract

We present the results of investigations on the actively and passively Q-switched diode-pumped solid state lasers. The 4.4 mJ output energy of 100 W quasi-cw diode bar pumped Nd:YAG laser and 38% slope efficiency were obtained in free-running mode. In electro-optically Q-switched operation we obtained a monopulse of 1.2 mJ energy and a pulsewidth of 5.8 ns, which corresponds to 206 kW of pulse peak power. The pulses of energy of 0.41 mJ and pulse duration of 8 ns were obtained in the passively Cr⁴⁺:YAG Q-switched Nd:YAG laser. Single frequency passively Q-switched end pumped by 10 W fiber coupled diode bar Nd:YAG laser with output averaged power of about 1 W and pulse peak power of about 1 kW has been demonstrated. LiF(F^-₂) and Cr⁴⁺:YAG crystals were applied as passive Q-switches. Investigations of pulse duration, repetition rate, energy, power and spectrum in the Fabry-Perot interferometer were performed.
