Intensity Dependence of Stationary Energy Transfer in Codirectional Photorefractive Two—wave Mixing
LIUJinsog, LIANGChanghong
Abstract
The intensity and phase formulas that are valid for the saturation and inter-mediate regime(before saturation)are derived,and the analytical expressions with the ration of saturation intensity to total incident intensity as their explicit variable are obtanied.The intensity depenence of stationary energy transfer in photorefractive acodirectional two-wave mixing is examined.It is necessary to using these formulas in some problems,such as the temperature of intensity dependence of two-wave mixing.A method of measuring exponen-tial gain coefficient is presented,which is suitable for two-wave mixing in intermediate regime.
