摘要: 介绍了在CFBR-Ⅱ脉冲堆上进行的3He-Ar-Xe体系的激光演示实验。当热中子注量率6×1014/cm2·s,气体组配3He:Ar:Xe=34.7:34.7:0.267(kPa)时,获得波长λ=1.73μm、脉宽(FWHM)平均值738μs、峰值功率为毫瓦级的激光输出。同时对测得的光信号及其特性进行了分析。Abstract: Lasing tests of a 3He-Ar-Xe system 3He:Ar:Xe=34.7:34.7:0267(KPa) on the CFBR-Ⅱ reactor is introduced.The wavelength and FWHM of the laser we observed are l.73μm and 738μs. The peak power is milliwatts when the flux of thermal neutron is 6×1014/cm2·s. The laser characterisitics are also analysised.
