SELF-PUMPED PHASE CONJUGATION IN A RING CAVITY AT 1.06 MU-M IN CW AND NANOSECOND REGIMES USING PHOTOREFRACTIVE BATIO3-RH

摘要

We present self-pumped phase conjugation experiments in a ring cavity at 1.06 mu m in a BaTiO3:Rh crystal both in the cw and in the nanosecond regime. The measured reflectivities are respectively 50% and 66%. At 4 W cm(-2) of cw illumination, it only takes 90 s to reach the steady state. A preliminary experiment of correction of the focusing effect of a lens is reported. (C) 1997 Elsevier Science B.V. [References: 9]
