we have recorded reflection gratings (RG) in ZWK-2TBp, ZWK-3p, WE-3b and ZWK-3b molecular azobenzene glassy films by 532 and 633 nm laser beams (corresponding to Λ=0.182 μm and Λ=0.216 μm, respectively). The results of measurements were compared with the transmission grating corresponding parameters at Λ=2 μm. The highest diffraction efficiency DE=0.91% has been achieved in ZWK-2TBp film when RG was recorded at 532 nm and read out at 633 nm. Generally, RG recording efficiency was about 10 times lower than in the case of transmission gratings with Λ=2 μm. No evidence of the dominant Rayleigh scattering effect was obtained. Unexpected possibility was found to use light of considerably different wavelengths (532 and 633 nm) for recording and readout of RG. DE at 633 nm was not only smaller but even higher than at 532 nm.
