Abstract
A method for attenuating an unpolarized laser beam includes separating the laser beam into two plane-polarized beams. The plane-polarized beams are polarization rotated. Each of the polarization-rotated beams is separated into two plane-polarized portions. One of the portions of one polarization-rotated beam is combined with one of the portions of the other polarization-rotated beam to provide an attenuated output-beam.
