摘　　要：大功率泵浦DPL的被动调Q技术一直是研究的重点。通过对被动调Q的理论分析,以及在大功率条件下,以初始透过率T0为自变量对输出脉冲序列特性进行数值分析,得出了相应的图表。可以看出随着初始透过率的增大,脉宽和重复率都增大,同时峰值功率减小。将被动调Q与声光调Q加以比较,得出被动调Q技术适用于大功率泵浦DPL的结论。It is an important task to study the passive Q-switching used in DPL high power pumped. The theory of the passive Q-switching is discussed. When DPL was pumped by high power, the characteristics of output plus series were evaluated as the function of the argument T0, which was small-signal transmittance. The results are shown by the curves that plus width and repetition rate increase and peak power decreases, when small-signal transmittance increases. The comparison results of passive Q-switching and one of A-O Q-switching show that passive Q-switching is applicable to DPL high power pumped.
