摘要：

The photorefractive properties of single crystals of the organic material 2-cyclooctylamino-5-nitropyridinedoped with 7, 7, 8, 8-tetracyanoquinodimethane are investigated with two-wave mixing experiments. Refractiveindexgratings with an amplitude of up to 1.8 ° 10−6 could be recorded for grating vectors along the twofoldaxis. The phase gratings showed a phase shift of between 20° and 70° with respect to the intensity grating.An experimental procedure for determining phases and amplitudes of absorption and phase gratings is discussedin detail. © 1990 Optical Society of America.
