Abstract
Bacteriorhodopsin (BR) films have a very low saturation intensity (~ 10 mW/cm2). Once the grating is read out during the recording process with a weak additional noncoherent beam, a saturable absorption describes the experimental diffracted beam kinetics to a high degree of approximation [1]. The self-diffraction of recording beams is much different from the diffraction of the readout beam. The first-order self-diffraction holographic kinetics in Raman-Nath thin grating conditions on BR-film shows considerable promise for the object motion detection [2]. In this work, the self-diffraction kinetics in the saturation region of BR-films are simulated using self-matched orders of Raman-Nath diffraction. We report numerical and experimental results for this case.
