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

摘要

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 laserbased 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.
