Mj. Chi et al., ENHANCED PHOTOREFRACTIVE PROPERTIES OF A RH-DOPED BATIO3 CRYSTAL AT ELEVATED-TEMPERATURE, Chinese Physics Letters, 14(11), 1997, pp. 838-841
Two-beam coupling and self-pumped phase conjugation properties of a Rh
-doped BaTiO3 crystal were investigated at 633 nm as the temperature w
as increased from 20 to 50 degrees C. A significant decrease in respon
se time and an increase in gain of two-beam coupling were obtained. Th
e self-pumped phase conjugation reflectivity was increased from 45 to
64 % in this temperature range.
