摘要：

Optical phase conjugation in gelatin film doped with basic green 1 has been measured using CW laser radiation (lambda = 632.8 nm) generated by He-Ne laser of total power 35 mW. The degenerate four-wave mixing (DFWM) experiment allowed for measurement of phase conjugate reflectivity as a function of dye concentration, backward beam intensity, forward beam intensity, probe beam intensity, mean pumping beam intensity and angle between the forward pumping beam and probe beam. For 1 mM concentration of basic green 1-doped gelatin film, 0.1% phase conjugate reflectivity has been observed. (c) 2006 Elsevier Ltd. All rights reserved.
