Abstract
The authors demonstrate a highly compact, passively Q-switched Nd:YVO4 laser using an uncoated GaAs wafer as a frequency-dependent output co upler as well as a saturable absorber. Owing to the Fabry-Perot effect , the effective reflection coefficient of the GaAs mirror is 0.7. The coupled-resonator cavity results in an intrinsic single-frequency oper ation. Under 1.4W optical pumping, 9ns pulses at a repetition rate of 125kHz in a single-longitudinal and transverse mode were obtained.
