Abstract
In a degenerate four wave mixing system, the phase conjugate signal from a transmission grating recorded in a Bi12SiO20 crystal is measured at various temperatures and the results are compared with theory. The diffraction efficiency η has a maximum value at a temperature above room temperature. The dynamic range in η vs It improves with increasing temperature, where It is the total intensity of the laser beam incident on the crystal. The experimental results are interpreted in terms of the temperature dependence of the effective modulation depth of the transmission grating and the diffusion field in the crystal.Keywords
