Abstract : The photorefractive tungsten bronze SBN:6O and BSKNN-2 crystals were investigated for sensor protection applications with considerable success. Our best photorefractive crystals exhibit response times of approximately 10 microseconds with coupling > 25/cm. This fast response was achieved using suitable dopant combinations, external field and focusing the incoming 1W/sq cm laser beam. Prototype limiters based on these photorefractive crystals have been tested at the University of Arkansas and their overall performance is promising for sensor protection applications. (MM)
