Shack — Hartmann wavefront sensor for measuring the parameters of high-power pulsed solid-state lasers

Abstract

The wavefront of the radiation of two types from high-power solid-state (Ti:sapphire and Nd:glass) lasers is experimentally studied. The measurements are performed using a Shack — Hartmann wavefront sensor. The technical and functional potential of this sensor in measuring laser-based schemes is demonstrated. The results of measuring both static and dynamic wavefront aberrations are discussed. The estimated dynamics of defocus aberration is in agreement with the experimental data.
