Abstract
We study the optical nonlinear properties of bulk Cd0.13Zn0.87Te monoc rystals at room temperature near the band gap. In time-resolved test a nd pump experiments, they manifest themselves by a defocalization and an induced absorption of the test beam in the presence of the pump bea m. By measuring the spatial intensity profile of the test pulse transm itted through the sample, we determine the real and the imaginary part s of the refractive index as functions of the photon energy and time d elay between pump and test pulses.
