Paper Abstract

Passive Q-switched operation of a LD-pumped Nd:YVO4 laser is studied with a saturable absorber GaAs as a passive Q-switched component and F-P output coupler. Q-switched pulses with pulse duration 47ns, pulse repetition rate 1183 kHz, pulse average power 430mW and beam quality M2=1.13 in a TEM00 mode were produced with Q-switched pumping threshold 1700mw. We performed numerical calculations of coupled wave equations for case of GaAs playing the role as mentioned above, discussing passive Q-switched mechanism and the dependency ofpulse duration and pulse repetition rate on pumping rate, which was well in agreement with the experiments' results. A brief and effective technique for compact Q-switched solid-state laser having multiple functions is provided.
