Abstract

A laser diode directly coupled CW Nd:YVO4 laser is reported. The pump threshold of about 22 mW and the maximum output of about 172 mW in TEM00-mode are obtained with a slope efficiency of 35. 8 percent. By using a Cr4+:YAG chip in the laser cavity as a saturable absorber, a laser diode continuously pumped Nd:YVO4 laser is passively Q-switched for the first time. haser pulses of 114 ns duration are produced with a repetition rate of as much as 380 kHz.
