An extremely stable Michelson interferometer with an optical path difference up to several thousand meters has been developed for the precise investigation of the frequency behavior of lasers. The theoretical value for the spectral resolution is of the order of 10(12). The spectral resolution of a real system is determined by external disturbances and was measured to be close to 10(1l). The capability and the characteristics of the system are discussed.
为了精确研究激光的频率特性，已经研制出一种光程差可达数千米的极其稳定的迈克尔逊干涉仪。光谱分辨率的理论值约为10的12次方。实际系统的光谱分辨率由外部干扰决定，经测量接近10的11次方。本文讨论了该系统的性能和特点。
