| Abstract: | Potassium lithium niobate crystal doped with copper was grown with Czochralski method. The infrared transmission spectra were measured. The reason why OH absorption peak turn to red shift was researched. The photorefractive erasure line was obtained using two wave coupled light path. The erasure time and photoconduction were calculated and the photorefractive properties of Cu:KLN crystal were studied. |
