摘要

目前，二极管激光器广泛应用于光电子领域，特别是基于激光干涉测量的精密测量。激光波长稳定性是激光测量的一个关键特性。由于激光波长容易受到环境和驱动电流的影响，因此对二极管激光波长的实时监测和标定对于干涉测量非常重要。本文研制了一种用于二极管激光干涉测量的实时波长监测与校准系统。建立了实验系统并进行了实验，验证了系统的可行性。

Wavelength calibration system for diode laser

Currently the diode laser is widely used in the field of optoelectronics, especially in precise measurement based on laser-interferometry. Laser wavelength stability is a property that critical to the measurement. Since the laser wavelength is easy to be influenced by the environment and drive current, real-time monitoring and calibration of diode laser wavelength is extraordinary important for interferometry. In this paper, a real-time wavelength monitoring and calibration system for diode laser based interference measurement were developed. The experiment system was built and conducted to verify the feasibility of the system.
