Technology of XeF blue-green laser with repetitive rate

Taking advantage of the technique of surface discharge optical pumping, a XeF(C-A) laser which can operate in the repetition mode is developed. The maximal repetitive rate is up to 10 Hz. The influence of repetitive rate and gas flow rate on the stability of output energy is studied and the main factors which influence the stability of output energy are analyzed. The experimental results show that increasing the gas feed rate into laser chamber can improve the stability of output energy. The ideal output energy results of 20 laser pulses under different repetitive rate and optimal experimental conditions are given. Output energy more than 4 J and better stability can be obtained when laser device runs at 1, 2 and 5 Hz, respectively. When the gas feed rate is larger than 53 L/s, the stabili
