Abstract

The laser wavefront compensation system (LWCS) is a closed-loop adaptive optics sytem whose purpose is to clean up optical aberrations in low power visible laser beams. The LWCS employs no moving parts and operates with either continuous-wave (CW) or pulsed inputs. In the pulsed mode, it will operate asynchronously over a wide range of pulse rates. The electronic data processing is entirely digital, including the wavefront reconstruction function. The deformable mirror employs a square array of 64 actuators, with a wavefront correction capability of ±600 nanometers. This paper describes the operating principles and hardware of the LWCS, together with data on the performance of the system.
