Carbazole-based bi-functional photorefractive polyphosphazene for correcting the laser wavefront distortion

Abstract

Carbazole-based polyphosphazene containing nitro azo chromophore moieties was synthesized first. The photorefractive polyphosphazene was prepared to optical qualitative films and used to correct the laser wavefront distortion under the room temperature without external electric field, pre-poling and addition agent. The results indicate that the photorefractive polyphosphazene film can correct both the diffraction distortion and phase distortion of the laser wavefront. At the same time the high-resolution laser wavefront distortion correction can be achieved. Further, as the result of the effectively correction of the diffraction distortion, the polymer film may be applied in microscale direct image.
