Abstract :
Shack-Hartman wavefront sensor for scientific investigations of wave fronts is represented in paper. It was shown that this type of wavefront sensor has multifunctional possibilities to measure laser radiation. Aspects of accuracy measurements increasing and dynamic range expansion are discussed.Samples of schemas and results of wavefront measurements to high power solid state lasers are presented.
