Abstract
A modified method of measurement of induced thermal lens parameters is proposed. Focal lengths of a thermal lens formed in laser-pumped fors terite crystals with (100) and (101) orientations are measured.and its astigmatic properties established. The choice of the method and of th e theoretical model proposed for determination of parameters of therma l lenses induced in Mg2SiO4:Cr crystals is experimentally confirmed by a substitution of a lens with known focal length for the forsterite s amples and also by the results of laser experiments.
