A diode-pumped Nd:YAG laser is passively Q switched by using F(2)(-) color centers in lithium fluoride as a saturable absorber. When cw pumped with a laser diode, the laser produces pulses of 20-30-nsec duration at 1064 nm, with an energy of as much as 20 microJ and a peak power of more than 1 kW. Data are presented on pulse width, energy, and repetition rate as a function of pump power. When the laser is operated at high pulse energy levels, a gradual bleaching of the saturable absorber is observed.
采用氟化锂中的F(2)(-)色心作为可饱和吸收体，对二极管泵浦的Nd:YAG激光器进行被动调Q。当用激光二极管连续泵浦时，该激光器在1064 nm波长处产生持续时间为20 - 30纳秒的脉冲，能量高达20微焦，峰值功率超过1千瓦。给出了脉冲宽度、能量和重复率随泵浦功率变化的数据。当激光器在高脉冲能量水平下工作时，可观察到可饱和吸收体的逐渐漂白。
