Ni. Koroteev et al., ON 2 RELAXATION-TIMES OF CUBIC NONLINEARITY IN SELF-ACTION OF LIGHT IN AN ISOTROPIC GYROTROPIC MEDIUM, Laser physics, 4(6), 1994, pp. 1190-1191
Relying on the investigation of polarization self-action of a laser pu
lse in a nonlinear optically active liquid, we propose a method for de
termining the difference of orientation relaxation times of intensity-
dependent additives to the refraction indices for circularly polarized
waves.
