中文摘要:
对780nm声光调制器(AOM)的温度响应进行了详细的理论计算,发现AOM衍射光偏振角的温度响应系数远大于衍射效率和衍射角的温度响应系数。针对AOM衍射光偏振角的温度响应,在地面实验室环境下对其进行了实验验证。在空间微重力环境下,AOM的温度响应可能会成为制约空间项目光学平台工作温度范围和性能指标提高的主要因素之一。基于AOM在实际空间应用中的脉冲工作模式,通过仿真建模给出了AOM声光晶体温度随环境温度的变化曲线,并给出了优化措施。

英文摘要:
Temperature response of 780 nm acousto-optic modulator(AOM)is calculated theoretically in detail.The research shows that the temperature response coefficient of polarization angle of diffraction light of AOM is much larger than that of diffraction efficiency and diffraction angle.Aiming at the temperature response of polarization angle of diffraction light of AOM,it is experimentally verified in the ground laboratory environment.In space microgravity environment,temperature response of AOM may become one of the main reasons that restricts the improvement of the operating temperature range and performance index of optical platform in space program.Based on the pulse working mode of AOM in practical space application,the variation curve between the temperatures of the acousto-optic crystal in AOM and environmental temperature is given by simulation modeling.And the optimization measures are given.
