A SCANNING FABRY PEROT INTERFEROMETER FOR LASER MODE ANALYSIS

Abstract

A high resolution scanning Fabry Perot interferometer was constructed for the purpose of spectral analysis of gas laser radiation. The performance of the interferometer is evaluated and a finesse in excess of 250 is noted. Matching requirements and alignment procedures for application of the scanning interferometer are summarized. The results of application of the interferometer to engineering problems and laboratory measurements including visual display of laser modes, determination of frequency stability and frequency drift, and studies of the FM Laser system are reported. High resolution photographs of typical FM Laser spectra are presented showing a 10 to 1 improvement over previous results in the program, thus emphasizing the value of such ain interferometer to state of the art developments in optical communications.
