【摘要】：为了实现中红外探测器绝对光谱响应度高准确度的测量,从理论和实验上研究了中红外波段激光的功率稳定性的提高和光束质量的优化方法。采用声光调制和反馈控制的方法,把中红外激光的功率稳定性提高到0.1%以内;根据高斯光束传输理论计算了所需空间滤波器的各项参数,设计了中红外空间滤波器,搭建了相应的实验装置,显著提高了中红外激光光束质量。为中红外绝对光谱响应度的高准确度测量提供了一个可靠的中红外波段激光光源。
[Abstract]:In order to measure the absolute spectral responsivity of the mid-infrared detector with high accuracy, the methods of improving the power stability and optimizing the beam quality of the mid-infrared laser are studied theoretically and experimentally. By using acousto-optic modulation and feedback control, the power stability of the mid-infrared laser is improved to less than 0.1%, and the parameters of the required spatial filter are calculated according to the Gao Si beam propagation theory, and the mid-infrared spatial filter is designed. A corresponding experimental device has been set up to improve the beam quality of mid-infrared laser. A reliable mid-infrared laser source is provided for the high accuracy measurement of the absolute spectral responsivity.
