摘　　要：通过采用多级Ｌ－Ｃ峰化回路、增大输出镜反射率、改变ＨＣｌ浓度的方法，使ＸｅＣｌ准分子激光的脉冲宽度达到１５０ｎｓ以上（最大脉宽达１７５ｎｓ），单脉冲能量大于１２０ｍＪ。同时对紫外准分子激光的光纤耦合系统进行了研究，直径为０．４，０．６，０．８，１．５ｍｍ的紫外石英光纤的耦合输出能量分别为１０，２９，３９。XeCl laser pulse durations longer than 150 ns have been achieved by using a multiple stage L C sharpening circuit, increasing reflectivity of the output coupler, and adjusting concentration of HCl in the mixture of Xe/HCl/Ne. The longest pulse duration was up to 175 ns. The output energy per pulse was above 120 mJ. The study on optical fibers coupling of UV excimer laser was made . The coupling output energies of 0.4, 0.6, 0.8, and 1.5 (Diameter mm) UV silica optical fibers were 10, 29, 39, and 58 (mJ),respectively. It has made encouraging the first attempt for China made excimer laser applications in laser medicine field, particularly in laser angioplasty.
