ABSTRACT:
A laser wavefront control system employs a common optical path and common high-power deformable mirror to optically compensate an incoming beacon or retroreflected return beam and a laser sample beam, in which the phase conjugate of the laser sample beam is impressed on a low-power deformable mirror. This control system drives the high-power deformable mirror, and has as its input the phase modulation required for compensation of optically sensed wavefront phase errors.
