摘要：

Holographie studies in azobenzene side-chain polymers reveal light-induced periodic surface reliefs at temperatures far below the glass transition temperature. We performed experiments with two-color holography on an azobenzene polymer. An intensive and linear polarized homogeneous blue pump beam illuminated the sample, and two red beams - outside the trans-azobenzene absorption - were used to inscribe the grating. A surface relief was obtained only with the pump beam on and only if its polarization was perpendicular to the writing beams. The findings are discussed in the frame of a recent mean-field model. © 2001 Optical Society of America.
