| 摘 要： | 以氮为稀释剂的电激励连续波HF/DF化学激光器可以使用低温吸附泵代替传统的机械真空泵和洗消装置，大幅度降低激光器的系统体积和重量。使用小信号增益测量系统对某超音速氮稀释电激励连续波HF化学激光器的增益分布进行了测量。得到了在4种不同激光功率下P1(4),P1(6), P2(4)～P2(6)谱线的增益系数分布曲线。测得P2(4)为最强增益谱线，最大值为0.1 cm-1；最强增益位置与最佳光轴位置相符；超音速气流使增益区延伸达2.5 cm。

| Abstract: | Cryogenic adsorption technique may replace machinery pump and exhaust processing system,hence nitrogen dilution is used in discharge-driven continuous wave(CW) HF/DF chemical laser,which can greatly reduce the size and weight of laser system.The gain distribution of supersonic discharge-driven CW HF chemical laser is measured by small signal gain measurement system.Gain distribution curves of P1(4),P1(6),P2(4),P2(5),P2(6) are obtained at four different laser power,and the highest gain spectral line is P2(4)... |
