摘要：
A passively Q-switched 1064-nm laser pulse was generated when a quasi-cw laser diode beam with a pulsewidth of several hundreds of microseconds pumped a Nd:YAG crystal. A Cr:YAG crystal was used as a saturable absorber. The temporal delay between the onset of the laser diode pump and the Q-switched output pulse was studied as a function of the initial transmission of Cr:YAG for several output couplers with different reflectivities. By pumping the Nd:YAG laser with a quasi-cw laser diode, we could actively control the pulse repetition rate of the passively Q-switched Nd:YAG laser. Also, the temporal jitter of the Q-switched pulse for the cw-laser-diode-pumped case could be reduced by using quasi-cw pumping. The temporal width and the peak power of the Q-switched pulse for the quasi-cw-pumped case were compared with those for the cw-laser-diode-pumped case.
