| Abstract: | The enhanced infrared photorefractive effect in cubic crystal GaAs under externally applied electric field is described. The spatial amplitude and phase variations of space charge electric field in the two-beam coupling process are emphatically analyzed, which quite well explain the results of experimental measurement |

| Keywords: | Infrared photorefractive effects gallium arsenide (GaAs) optical coupling. |
