Aa. Kovalev et al., PHASE-CONJUGATION IN DYE-ACTIVATED NEMATI CS IN THE FIELD OF PULSED RUBY-LASER RADIATION, Kvantovaa elektronika, 22(8), 1995, pp. 838-840
Phase conjugation of radiation from a free-running ruby laser by a the
rmal nonlinearity of dye-activated nematics was demonstrated. The conj
ugation coefficient was R similar to 100% near a phase transition to t
he isotropic state. The temperature dependences of R were investigated
theoretically and experimentally.
