本文研究了从长激光器获得单频输出的问题，并对两种方法进行了实验研究。第一种方法包括使用外部滤波器来选择多个振荡模式中的一个。第二种方法包括在内部抑制不需要的谐振，使得激光振荡只能在单一频率下发生。本文指出，采用第二种方法，在许多情况下可以获得更大的功率，并报道了在6328 A He-Ne激光器上获得15 mW单频输出的实验结果。
The problem of obtaining single-frequency output from a long laser is considered, and two methods are investigated experimentally. The first method consists of using an external filter to select one of a number of oscillating modes. The second method consists of suppressing internally the unwanted resonances so that the laser oscillation can only take place at a single frequency. It is shown that with the second method one can in many cases obtain greater power, and experiments are reported in which single-frequency output power of 15 mW was obtained from a 6328 A He-Ne laser, A simple feedback circuit is described for stabilizing the frequency of the laser oscillation.
