Adaptive optical system for ICF application

An adaptive optical system has been built for improving optical beam quality in a new inertial confinement fusion (ICF) system. This system is designed to compensate the static and dynamic wavefront errors in the laser generator and amplifier by pre-compensation manner, which includes a 45-channel deformable mirror, two Shack-Hartmann wavefront sensors with 10x10 sub-apertures, a 45-channel high voltage amplifier and a wavefront control computer. Preliminary principle experiment has been done and the experimental results are reported.
