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
