The authors report a study of transient phase grating in InSb at room temperature induced by two-photon absorption of pulsed CO/sub 2/ laser radiation. From these results, the authors deduce a value of the ambipolar diffusion coefficient D approx. = 26 cm/sup 2/ . s/sup -1/. The behavior of the grating and the change of refractive index confirms the free-carrier plasma being dominant in the modulation of nonlinear optical properties.
