In this work, we have experimentally studied unfocused and focused holographic grating (HG) recording in an azobenzene molecular film B11 with linear p-p and orthogonal circular L-R polarizations of recording and readout beams , and with HG periods of 2μm and 10 μm. HG diameters were 1.17mm and 0.14mm for unfocused and focused HG, correspondingly. Measurement technique of laser beam diameters was developed, especially useful for focused laser beams. It was found that for certain recording beam polarizations and HG period focusing diminishes recording efficiency (REF factor) including diffraction efficiency decrease 2 to 8 times. L-R recording is more efficient than p-p recording in both cases. HG period effect on recording efficiency is different for unfocused and focused recording. Recording efficiency is higher for 10 μm in the case of unfocused recording, and it is higher for 2μm in the case of focused recording.
