Time evolution of the photoanisotropic phase shift on illumination with a 20 mW linearly polarized Ar laser beam at RT.
Dependences of the photostationary values of on the temperature for pump beam intensity 20 mW (curve 1) and 1 mW (curve 2).
Changes in the value of when the pump intensity alternates between 1 mW (point “1”) and 20 mW (point “2”) at constant temperatures: (a) , (b) , (c) .
Dependence of on the temperature.
