一、引言 在许多应用中,例如激光通讯、激光光谱仪、激光多普勒干涉仪等,都要求在一个相当长的时间内,输出波长十分稳定。环境条件,诸如温度变化、机械振动等,都会妨碍长时期的稳定性。本文介绍了一种基于标准具原理,用于脉冲或连续波激光器的简单波长稳定系统的设计和工作特性。该系统可以提供长时期的波长稳定性,不需要计算机进 I. INTRODUCTION In many applications, such as laser communication, laser spectroscopy, laser Doppler interferometer, etc., require a very long period of time, the output wavelength is very stable. Environmental conditions, such as temperature changes, mechanical vibrations, etc., can hinder long-term stability. This article presents the design and operating characteristics of a simple wavelength stabilization system based on the etalon principle for pulsed or continuous wave lasers. The system can provide long-term wavelength stability, without the need for computer into
