Research on the transmission characteristic of angle tuning F-P etalon

The dualistic transmission model of F-P etalon for angle and frequency has been built to analysis and build the relationship of transmission variation with angle and frequency. In the experiment, the transmission variations with frequency under different angles have been researched with the frequency rapid tunable fiber laser to gain the peak transmission, full width at half height, and relative sensitivity of transmission spectra. By comparing the experimental results and theory analysis, the uniformity of above parameters has been proved. The result of this paper can be used to design F-P etalon.
