Self-defocusing in CdSe induced by charge carriers created by two-photon absorption.
We observe self-defocusing of picosecond, 1.06-microm pulses in CdSe. The effective nonlinear refraction can be 2 orders of magnitude larger than that of CS(2). We obtain good agreement with the theory presented here, which assumes that the self-refraction is caused by charge carriers created by two-photon absorption.
