Enhanced self-pumped phase conjugation from 16°-cut KNSBN:Cu

Abstract
With the maximum coupling coefficient and high internal reflection conditions, the self-pumped phase-conjugation reflectivity of copper-doped potassium sodium strontium barium niobate (KNSBN:Cu) is increased with 16°-cut samples. The response time is also shortened. The resolution property of 16°-cut KNSBN:Cu is determined and a distorted image is corrected by using the 16-cut sample.
