Claims
- 1. An arrangement for monitoring the power delivered by a photon channeling element, comprising:
an integrating chamber to receive an output end of said photon channeling element and an optical surface positioned to reflect a portion of the laser-light exiting said photon channeling element at substantially normal incidence to the beam centerline, wherein said integrating chamber may be adapted to collect substantially all of the laser-light reflected from said optical surface; and a sensor in optical contact with a portion of said integrating chamber that is out of the path of laser-light reflected from said optical surface.
- 2. The arrangement of claim 1, wherein said integrating chamber is adapted to scatter and re-scatter light reflected from said optical surface within the integrating chamber.
- 3. The arrangement of claim 1, wherein said integrating chamber is adapted to scatter and re-scatter light reflected from said optical surface within the integrating chamber in a manner to provide a substantially even ambient light illuminating the integrating chamber.
- 4. The arrangement of claim 3, wherein said sensor is be configured to detect at least a portion of the ambient light illuminating said integrating chamber that is not directly reflected from the optical surface.
