Abstract

See full text

A unit for measuring a power of randomly polarized light beam is configured with spaced first and second beam splitters having respective reflective surfaces which face one another and configured to sequentially reflect a fraction of randomly polarized beam which is incident upon the first splitter. The beam splitters are dimensioned and shaped so that an output beam, reflected from the second beam splitter, has a power independent from the state of polarization of the randomly polarized beam.
