A pair of copper bromide lasers in an oscillator–amplifier configuration was used to investigate the effect of the addition of hydrogen to the helium buffer gas on the small-signal gain ( g 0 ), saturation energy intensity ( E s ) and output power ( P out ) of the laser. The addition of a small amount of hydrogen to the He buffer gas in a CuBr laser caused approximately doubling of the amplifying parameters and average output power of the amplifier. The amplifying parameters and output power of the system were measured at different input electrical powers of the amplifier, and optimum input powers of 1.75 and 1.65 kW were obtained for He and He–H 2 gases, respectively. The maximum g 0 , E s and P out achieved are 0.068, 0.090 ##IMG## [http://ej.iop.org/images/1555-6611/30/9/095004/lpaba9dcieqn1.gif] {${\text{c}}{{\text{m}}^{ - 1}}$} ; 47.6, 77.1

向He缓冲气体中添加H 2对溴化铜激光器的放大参数和输出功率的影响

使用一对振荡器-放大器配置的一对溴化铜激光器，研究了向氦缓冲气体中添加氢对小信号增益（g 0），饱和能量强度（E s）和输出功率（ P out）的激光。在CuBr激光器中向He缓冲气体中添加少量氢会导致放大参数和放大器的平均输出功率大约翻倍。在放大器的不同输入电功率下测量了系统的放大参数和输出功率，对于He和He–H 2气体，分别获得了1.75 kW和1.65 kW的最佳输入功率。达到的最大g 0，E s和P out为0.068、0.090 ## IMG ## [http://ej.iop.org/images/1555-6611/30/9/095004/lpaba9dcieqn1.gif] {$ { \ text {c}} {{\ text {m}} ^ {-1}} $}; 47.6、77.1
