| Abstract: | 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. |
