Abstract:

The result of the investigation of the induced absorption in the photopigment glass by phase-modulated holographic method with additional phase metrical grating has been shown. The analytic expressions for the calculations of the induced absorption were obtained by second harmonic of the output beam intensity. The effect of the residual absorbing grating in the metrical phase grating has been found.
