摘要

A simultaneous self-Q-switched and mode-locked laser in a direct 885nm diode-pumped Cr,Nd:YAG crystal is demonstrated.An improvement of the slope efficiency (38.1％) in the absorbed pump power is obtained under direct pumping.Under the maximum output power of 3.36 W,the repetition rate of the Q-switched envelopes is 95 kHz and the corresponding pulse width is 400 ns.Almost 100％ mode-locked modulation depth is observed at the output power of 75 m W.The repetition rate of mode-locked pulses within a Q-switched envelope is 130 MHz,and the mode-locked pulse width stays within the scale of 500ps.
