Paper Abstract

Interferential approach to registration of space-energetical characteristics of laser radiation is based on reading due to interferometrical methods of changes of refractive index, appearing in specially chosen medium during transformation through it oflaser radiation. A short overviews of non-linear effects, which may be used for these purposes is demonstrated in work [ 1]. Most advanced nowdays is usage of heat effect [2, 3]. Presented work is devoted to research of possible interferential registration of laser beam profile at the expense of optical orientation of molecules in Kerr mediums and due to re-orientation effect of director of nematic liquid crystals (NLC) in the field of laser wave.
