Abstract

A simple and miniature Fabry–Perot interferometer composed of a graded-index rod is described. When the optical path length of the rod is scanned by temperature variation, the interferometer works as an element for observing the spectrum of a gas laser. With this element, we can readily determine the number of axial modes, their relative intensities, and the frequency separation between them.
