光栅外腔反馈半导体激光器及稳频系统的动态特性测试
Dynamic Response of the Grating-Feedback External Cavity Diode Laser and Frequency Stabilization System
摘要
Abstract
Frequency stability is one of the key issues when the diode laser work in the harsh environment.The mechanical structure design of the laser should to be optimized.The corresponding calibration based for the environmental system characteristics is more crucial.So,in order to obtain the dynamic response of the ECDL laser and its frequency stabilization system,an efficient and precise method to measure laser frequency fluctuation is demonstrated.After recording the system response to sinusoidal and square wave modulation,the amplitude frequency and the phase frequency characters are obtained by Fast Fourier Transform.The results show that the measurement scheme of the square wave modulating signal is consistent with sinusoidal wave modulating signal,it is more effective and does not need multiple measurements.Using the dynamic analysis system,the response of closed-loop system to mechanical shock is achieved.It can provide the experimental basis for the calibration and optimization of the system parameters in the similar environment.关键词
