Mechanism of photorefractive enhancement of photochromic gratings in BSO - Experimental results and phenomenological modelling
We report an increase of more than a factor of 100 in the diffraction efficiency from photochromic gratings written in BSO by uniformly illuminating these gratings with 488 nm light to induce secondary photorefractive gratings. Upon application of an electric field, the phase shift between the two g...
