title: Time-resolved self-defocusing in Cd(0.23)Hg(0.77)Te and InSb.
abstract: We describe an experimental study of self-defocusing in Cd(0.23)Hg(0.77)Te and InSb at room temperature using a hybrid CO(2) laser at 10.6 microm. The time-resolved transmitted temporal pulse profiles showed the effects of refractive-index changes of up to Deltan ~ 0.1 caused by the electronically induced optical nonlinearity. Thermally induced contributions due to dn/dT ~ -1 x 10(-3) K(-1) in CdHgTe were also measured.
