摘　　要：ＪＫ－１３型２ｋＷ横流式ＣＯ_２激光器，在每天漏气速率为０．４ｋＰａ～０．５３ｋＰａ的条件下，采用排气逐步降低工作气压和更新部分工作气体的方法，工作气体使用时间达５００ｈ以上，激光器的输出功率平均为１．６ｋＷ，电光转换效率平均为 １５％，工作气体还能继续使用。When the rate of gas leak was 0.4kpa-0.53kpa per day, Lizing progressively decreasing the working gas pressure and replacing the partial working gas,the working gas can be used more than 500h using JK - 13 across - flow CW 2kW CO_2 laser. An average output power of 1.6kW and an average efficiency of electro - optic conversion of 15% can be obtained, and the working gas can also be kept on using.
