摘要
A diode-pumped doubly Q-switched Nd∶YAG laser operating at 1064nm both with an acoustic-optical(AO)modulator and Cr4+∶YAG saturable absorber in the cavity is demonstrated.At the incident pump power of 11.8W the laser can generate stable 8ns pulse with the peak power of 23.6kW at a 10kHz repetition rate.The pulse temporal profile is more symmetric and shorter compared with that of passively Q-switched lasers with only AO-active and Cr4+∶YAG.A reasonable analysis is developed to explain the experimental results theoretically.
A diode-pumped doubly Q-switched Nd ： YAG laser operating at 1 064 nm both with an acousticoptical（AO） modulator and Cr^4＋ ： YAG saturable absorber in the cavity is demonstrated. At the incident pump power of 11.8 W the laser can generate stable 8ns pulse with the peak power of 23.6 kW at a 10 kHz repetition rate. The pulse temporal profile is more symmetric and shorter compared with that of passively Q-switched lasers with only AO-active and Cr^4＋ ： YAG. A reasonable analysis is developed to explain the experimental results theoretically.
