Abstract
Light-induced scattering in a Ce:Fe:LiNbO3 crystal is highly temperature dependent. By considering the effect due to thermally activated ions in a photorefractive crystal, we have shown that the photoinduced space-charge field is neutralized by the activated ions. This neutralization in turn leads to a reduction of scattering noise in the crystal. By raising the crystal temperature, we have observed a reduction in scattering noise, which is consistent with our prediction. The signal-to-noise ratio (SNR) in a two-wave mixing amplification due to thermal activation effect is analyzed. Experimental demonstrations using a Ce:Fe:LiNbO3 crystal are provided in which we have shown that the SNR improves as the crystal temperature increases.
