| 摘 要： | 对于频率不能连续调谐的CO激光器,采用一种新的激光频率稳定度的测量方法是以分子的激光磁共振谱线为基准,通过测量分子的激光磁共振谱线线宽及其变化,然后用阿仑方差进行数据处理,即得出了一系列时畴下的CO激光频率稳定度,并用计算机对取样时间从0.1秒-1000秒的频率稳定度进行幂函数拟合,获得了频畴的CO激光频率稳定度的表达式。

| Abstract: | Owing to the uncontinuously tunable property of CO laser, the frequency stability is very difficult to be determined by using direct molecular absorption spectrum. A new measurement method of laser frequency stability is proposed in this paper. The method is based on molecular spectrum of laser magnetic resonance (LMR). The variation of linewidth of molecular LMR spectrum were treated by Allan variance method. A series of CO laser frequency stabilities were obtained from 0.1s to 1000s. The frequency stabalities were fitted by power function in a computer. The expressions of frequency stabilities are found for stabilizing and free-running CO laser. |
