Mitigation of initial distortions of a laser beam when using radiation scattered at a screen to control for a flexible mirror

Atmospheric and Oceanic Optics volume 27, pages 366–371 (2014)Cite this article

Abstract

Results of atmospheric experiments on adaptive compensation of aberrations in the initial wavefront of laser beams of the visible and IR wavelength ranges are presented. The flexible mirror control signal was produced based on measurements of the average radiation power of a beam backscattered by a diffuse screen. It is shown that the compensation efficiency for initial aberrations of the wavefront increases with a decrease in the diaphragm of the scattered radiation receiver. The obtained experimental data agree with results of qualitative analysis of compensation efficiency achievable on the setup used in the experiments.
