Paper Abstract

This paper describes a phase-shifting, self-referencing, radial-shear (10:1) interferometer, designed for testing a pulsed XeC1 laser (308 nm) that has been Raman-shifted into the blue (459 nm). It is the first report of an implementation of a general class of phase-shifting interferometers without moving parts: the phase shift and separation of beams are obtained with a stationary diffraction grating. The presentation includes results from early ex-periments, a discussion of the good and bad aspects of this type of interferometer, and a review of the systems where its use might be appropriate.
