Abstract
We propose a two-wave mixing interaction between a self-bent pump beam and a signal beam in a BaTiO3 crystal. This new configuration exhibit s two-wave mixing gain values as high as G(sat) = 1.5 x 10(5), corresp onding to an enhancement of 40x in comparison with a conventional two- wave mixing geometry. Application to coherent image amplification with such a high gain combined with a very good signal-to-noise ratio is d emonstrated. (C) 1995 Optical Society of America
