Abstract
The influence of an external field on photorefractive recording in Sn2P2S6 (SPS) crystals is studied. A large gain factor of more then 15 cm-1 is achieved for a grating spacing of 12 μm at λ = 0.9 μm. For an applied field exceeding 0±200 V/cm a switching of the beam coupling direction is detected, exhibiting a pronounced hysteresis.
