中、远红外双波段激光器发射光谱测量与评估

摘要

在分析中远红外双波段(氟化氘与一氧化碳)激光器发射光谱的基本特征和分光型谱仪存在高级次光谱混叠等问题的基础上,选定Tensor37干涉型遥测光谱仪并利用黑体标定出仪器响应函数；对中、远红外双波段激光器光谱进行了模拟测量和实际测量,分析评估了双波段激光器的谱线成分、峰值变化、测量精度和相对强度等,为双波段激光器的介质参数计算、运转参数优化以及红外应用提供有效数据.%Remote sensing interferometer spectrometer Tensor37 was selected as measuring equipment based on spectrum characteristics of a middle infrared and long infrared dual-band (DF & CO2) laser on account of problems, such as blending of CO2 spectrum and the third level of DF spectrum, existing in grating monochromator and spectrophotometer. Simulating measurement and real measurement of dual-band laser spectrum were explored after validating blackbody radiation response function of Tensor37. Effective data including spectrum composition, peak fluctuation, wavelength accuracy and relative intensity were eval-uated for calculating gain media parameters, optimizing operating parameters and infrared application of dual-band laser
