Abstract

In this paper, we present a scheme of recording apodized grating using an additional laser beam polarized orthogonally to two recording beams. The additional beam has a function to control beam intensity modulation of the recording beams and, therefore, changes the saturated modulation amplitude of the grating. An investigation of the diffraction efficiency depending on the intensity modulation is implemented in DuPont’s HRF-150-38 photopolymer. As results of the experiment, holographic apodized gratings with uniform, inverse Gaussian, and triangular profiles are fabricated successfully in this material.
