Abstract

An uncoated optical wedge and two mirrors form the basis of a very simple unequal-path interferometer for laboratory use. The optical design is free of ghost reflections, works with any source polarization, and does not require optical isolation. The interferometer is inexpensive to make and easy to align, and may be used for coherence testing, wavelength stabilization, and optical testing.
