摘　　要：本文采用速率方程理论，比较全面详细地分析计算了脉冲钛宝石激光器的动力学特性。在实用参数范围内，给出了输出参数与泵浦参数的关系。采用这些结果可以统一解释以往文献报道的结果并与我们自己的实验数据相一致。According laser rate equations, the dynamic characteristics of pulsed Ti∶sapphire laser has been comprehensively studied. The theoretical study and experimental results prove, if duration of pumping pulse is much less the life of up energy level, (1) the width and waveform of the output pulse is independent of the pumping pulse, (2) the only factor of determining the output pulsewidth is the ratio of pumping energy to threshold pumping energy, (3) the time delay of output pulse is dependent of the pumping pulsewidth and the ratio of pumping energy to threshold pumping energy.
