Abstract
We report the photorefractive properties of a new kind of Cu-doped KNS BN crystal in which a small fraction of oxygen (O) atoms are replaced with fluorine (F) atoms. The replacement of oxygen with fluorine in Cu :KNSBN crystals leads to a much shorter response time of 30 ms at an i ncident intensity of 5 W/cm(2). We also discuss the effect of electron -hole competition on the coupling constant. (C) 1998 Optical Society o f America.
