| Abstract: | In this paper we report the results of two wave mixing experiment on pure and Cu doped KTNcrystals in tetagonal phase. Their gain coefficients were neasured to be 5. 6 and 6. 8cm~(-1). the diffration effi-ciencies are 34. 2% and 35%, respectively. The sign of the dominant charge carriers are determined to be posi-tive. Some other photorefractive parameters are calculated in this paper. |
