The dependence of the angle of the nonlinear total reflection on the power of the pump wave and the initial distance between the beams is determined. The reflection effects are studied for the interaction of the green (24 mW) and red (0.7 mW) laser beams that intersect at a relatively small angle (about 0.01 rad) in a 5-cm-long cuvette with the stained alcohol. The theoretical results are in good agreement with the experimental data.Keywords: A-thermal; Defocusing; Experimental data; Initial distance; Optical beams; Pump waves; Reflection effects; Theoretical result; Thermal nonlinearities; Total reflection; Laser beam effects; Reflection200910.1134/S1054660X090503992016-02-24
