Experimental Observations of Thermal-Blooming Compensation Using a Deformable-Mirror System

Abstract

A laboratory experiment has demonstrated the effectiveness of compensating for forced-convection-dominated CW thermal blooming by using a deformable mirror to add phase corrections to the laser beam. In agreement with theoretical predictions, the peak focal-plane irradiance has been increased by a factor of 3 under severely bloomed conditions.
