Abstract

The nonlinearity of phase-conjugate beam reflection with four-wave mixing in BSO crystal by the moving grating at large fringe modulation formed by the incident-beams ratio is investigated. The experimental results have shown that the optimum fringe velocity is the incident-beam ratio and the total-light-intensity dependent, the reflectivity at the optimum fringe velocity is the incident-beam ratio and the fringe-spacing dependent. Based on these nonlinear properties, the edge-enhancement of an object is achieved.
