Js. Zhang et al., Specular reflection enhancement and reduction from the surface of a photorefractive crystal in the presence of a "pump" beam, APPL PHYS L, 78(25), 2001, pp. 3986-3988
We demonstrate the enhancement and reduction of the-specular reflection fro
m the surface of a photorefractive crystal in the presence of a "pump" beam
. The pump beam could be the phase conjugate beam of the input beam or anot
her laser beam. The contribution of the reflection grating is also demonstr
ated in a 45 degrees -cut crystal. The change of the specular reflection wi
th-respect to the intensity ratio of the input beam to the pump beam is mea
sured. (C) 2001 American Institute of Physics.
