通过讨论连续波DF激光器谱线小信号增益随光腔温度和相对粒子数变化,指出随光腔温度和相对粒子数增加,谱线小信号增益最大值转动量子数和短波方向零小信号增益转动量子数向高转动态移动,且与一定范围的光腔温度和相对粒子数对应。整数零小信号增益转动量子数较难取得,结合实测光谱给出了替代条件:谱线短波方向相对强度最小截止转动量子数J L小信号增益大于零和假定转动量子数J L-1谱线小信号增益小于零。根据DF化学激光器实测光谱三个谱带所表征光腔温度范围相等,估算出某连续波DF激光器光腔温度范围为305~368 K,1P、2P和3P谱带相对粒子数范围分别为:1.77~2.09、1.65~2.05和1.19~1.72。
By discussing the small-signal gain of continuous-wave DF laser with the change of optical cavity temperature and relative particle number, it is pointed out that with the increase of cavity temperature and relative particle number, the maximum rotation of small signal gain and the small-signal gain of short- Quantum number to high rotational movement, and with a range of cavity temperature and the relative number of particles. Integer zero small signal gain rotation Quantum number is difficult to obtain, combined with the measured spectrum gives the alternative conditions: short-wave direction of the relative intensity of the line minimum cut-off rotation quantum number JL small signal gain greater than zero and the assumed quantum number of rotation JL-1 line Small signal gain is less than zero. According to the fact that the optical temperature ranges of the three bands of the DF chemical laser are the same, it is estimated that the temperature range of a CW DF laser is 305 ~ 368 K, the relative particle numbers of 1P, 2P and 3P are 1.77 ~ 2.09, 1.65 ~ 2.05 and 1.19 ~ 1.72.
