Abstract
A beam sampling system, includes a first beam splitter adapted to split a laser beam having a primary polarization component and a secondary polarization component, into a first intermediate sample beam, and a first beam splitter output beam, the intermediate sample beam including first percentage of the primary polarization component and a second percentage of the secondary polarization component. A 90-degree polarization rotator is positioned in the intermediate sample beam line. A second beam splitter is mounted so that the intermediate sample beam is split into an output sample beam on an output sample beam line, and a second transmitted beam, the output sample beam including substantially said first percentage of the secondary polarization component and substantially said second percentage of the primary polarization component.
