Abstract： The intensity response of an optically erased photorefractive two-wave mixing to the erase beam is studied by using the coupling wave equation and the band-transport model. The concepts of response strength and the minimum response intensity are introduced and their temperature dependence is investigated. A 2-fold increase in the response strength and 4-fold decrease in minimum response intensity have been experimentally observed in Ce:KNSBN at 633 nm when the crystal temperature is raised from 320 to 370K. These experimental results are in agreement with theoretical analysis and show that the response property can be improved by changing the crystal temperature.
