Abstract
Functionalized azo-carbazole compounds, when exposed to two interfering polarized coherent laser beams, show efficient mixed amplitude and phase recording ability, frequently accompanied with surface relief grating formation. The aim of the present work is to study the dynamics of grating recording in azo-carbazole compounds using 30 ps train of pulses (532 nm, 1.2 mJ). The build-up of diffraction gratings arising, due to repeated pulses, were probed by a He-Ne laser operating at 632.8 nm by measuring power of a first order of diffraction. The grating period amounted to Lambda = 0.76 mu m.
