摘要：

We demonstrate self-pumped optical phase conjugation in Te-doped Sn2P2S6, a semiconducting ferroelectric crystal, using a 1.06 mu m wavelength cw Nd:YAG laser. The photorefractive gain of this crystal has been increased to Gamma = (3.9 +/- 0.4) cm(-1) by Te doping. We observed self-pumped optical phase conjugation in a ring cavity scheme with phase conjugate reflectivities of more than 40 percent and a very fast phase conjugate rise time below 100ms at a light intensity of 20 W/cm(2). This is more than two orders of magnitude faster than in any other photorefractive crystal, as e. g. in Rh-doped BaTiO3. (c) 2005 Optical Society of America
