【摘要】：法布里-珀罗(F-P)干涉仪是具有重要科研和实用价值的光学仪器,能广泛应用于光学鉴频、锁频以及光谱超精细结构的测量研究。然而,在实际应用中干涉仪的频谱特性将受到诸多因素的影响。从入射光束发散角、入射光频谱、干涉仪平板吸收损耗、平板表面缺陷和不平行度等因素对F-P干涉仪频谱特性的影响做了深入的研究。在考虑了上述诸多实际因素情况下,理论上导出了F-P干涉仪的透射频谱函数的一般表达式;定量给出了由发散角引起的透射频谱整体平移量;提出了等效发射激光谱宽的概念,将入射光束发散角、入射光频谱、干涉仪平板表面缺陷和不平行度等对透射频谱的展宽效应合并处理,给出了定量的等效关系式。这些结果可为法布里-珀罗干涉仪的设计与应用提供借鉴。
[Abstract]:Fabri Perot (F-P) interferometer is an optical instrument with important scientific research and practical value. It can be widely used in the study of optical frequency discrimination, frequency locking and spectroscopic hyperfine structure. However, in practical applications, the spectrum characteristics of interferometer will be influenced by many factors. From the incident beam divergence angle, the incident light spectrum, the interferometer plate. The influence of absorption loss, flat surface defect and non parallelism on the spectrum characteristics of F-P interferometer is deeply studied. Under the circumstances mentioned above, the general expression of the transmission spectrum function of the F-P interferometer is derived theoretically, and the overall translation of the transmission spectrum caused by the divergence angle is given. The concept of the equivalent emission laser spectrum width is used to combine the incident beam divergence angle, the incident light spectrum, the surface defect and the non parallelism of the interferometer on the broadening effect of the transmission spectrum, and give the quantitative equivalent relation. These results can be used for reference for the design and application of Fabri Perot interferometer.
