Red-Green Diffraction Instability in the Photorefractive mixed Crystal Bi sub12, Ti sub 0.76, V sub 0.24, O sub 20,

Abstract

We have investigated the new doubly color sensitive photorefractive crystal Bi12Ti0.76V0.24O20 by writing a hologram in green (Lambda = 0.51 micron m, cw-argon laser) and reading it out in red (Lambda = 0.63 micron m, cwHeNe laser). It was found that the diffraction efficiency for the red beam is chaotically oscillating in time with a period of about 0.1 s between zero and some maximum. The diffraction efficiency for the red beam decayed smoothly after the green beam was switched off
