摘要

摘要: 研究了脉冲宽度为25~40 ns的放电脉冲XeCl准分子激光器的工作参数。结果显示,激光器产生的脉冲能量为0.2~0.7 J,重复频率为100 Hz,表明在泵浦功率为2.8~3.3 MW/cm3时,激光器实现了2.6％的激光效率和3.8％的本征效率。

Abstract: The working parameters of the discharge pulse-periodic XeCl lasers with pulse duration of 25-40 ns are researched. Results demonstrate that the lasers generate the pulses of radiation with energies of 0.2-0.7 J and operate with a repetition rate up to 100 Hz. It is shown that the total laser efficiency of 2.6% and the intrinsic efficiency of 3.8% are realized with the pumping power of 2.8-3.3 MW/cm.
