Paper Abstract

High energy laser systems usually attempt to focus a small spot of laser radiation on a distant receiver plane. Aberrations within the optical system, as well as in the intervening atmosphere (turbulence), tend to spread the size of the beam in the focal plane and reduce the peak irradiance that could otherwise be obtained. Adaptive optics technology in wavefront sensors and deformable mirrors can significantly reduce the phase errors on the laser beam and increase the laser fluence on the receiver plane. The key to making this work is being able to measure the optical distortions accumulated along the actual laser beam path. To obtain a wavefront on which to make this measurement, a wavefront sensor must optically share the full aperture of the optical path with the outgoing laser beam.
