【摘要】 用简并四波混频的方法观察了复合型硒化镓的相位共轭效应。测得在10.6μm波长处它的最大共轭反射率Rc=5％,饱和光强Is=16×10⁶W/cm²,三阶极化率X³=3.7×10^-9esu。三阶极化率和饱和光强的数值与James等人的价带跃迁理论计算结果相符。更多还原

【Abstract】 Phase conjugate signal in the combination-type GaAs using degenerede four-wave mixing at 10.6/um was observed.We found the maximum phase conjugate reflectivity Rc=5% and the saturation intensity Is=16×106W/cm2.The value 3.7×10-9esu of the third-order nonlinear susceptibility x(3) derived from the measurements was agreed with the theory of James and Smith for x(3) which is due to intervalence band transition.更多还原
