  • Patent number: 7706069
    Abstract: Apparatus for attenuating an unpolarized laser beam includes a polarizing beamsplitter for separating the laser beam into two plane-polarized beams following separate paths. The two plane-polarized beams are polarization rotated by a single polarization rotator. Each of the polarization-rotated beams is separated by a polarizing beam-combiner into two plane-polarized portions. One of the portions of one polarization-rotated beam is combined by the beam-combiner with one of the portions of the other polarization-rotated beam to provide an attenuated output-beam. In certain examples of the apparatus the separate paths are made equal in length so that combined beam portions are equal in diameter.
