Abstract
Experimental observations of the power transfer effect between two writing beams in dry methylene-blue-sensitized gelatin films are presented. A low-p ower He-Ne laser is used for the realization of two-wave mixing. The influe nces of the writing angles and the polarization of the writing beams on the holographic enhancement coefficient, which shows the magnitude of the powe r transfer, are demonstrated. The diffraction efficiency was 0.4% and the h olographic enhancement coefficient 0.16.
