Abstract

Passively Q-switching and mode-locking has been realized in a diode-pumped Nd:YAG laser using a GaAs wafer as an output coupler as well as a saturable absorber. The laser has a Z-type cavity to achieve a tight-focused beam at the saturable absorber and to realize an optimum mode matching in the laser crystal simultaneously. At an incident pump power of 13.8 W, the average output power was 1.62 W. The repetition rate and pulse width of the Q-switched pulses are in the range of 29 to approximately 73 kHz and 0.73 to approximately 1.87 microsecond(s) , respectively. The mode-locked pulses were measured to have a repetition rate of 154 MHz and an average pulse duration of 42 ps.
