Parametric generation and phase conjugation of intersecting laser beams in a layer of a nematic liquid crystal containing a dye
Parametric generation has been obtained for stimulated forward scattering of counterpropagating beams of radiation from a Nd3 + : YAG laser in a layer of nematic liquid crystal containing a dye. Calculations show the possibility of self-pumped phase conjugation of the wave front of a beam with a diffraction spreading length that is comparable to the dimension of the region of self-intersection in the nematic liquid crystal with a thermal nonlinearity. Self-pumped phase conjugation of the wavefront of quasi-cw radiation has been obtained.
