Paper Abstract

Nonlinear optical and carrier dynamics of CdMnSe and CdMnTe were studied using picosecond pulses from a mode-locked, Q-switched Nd:YAG laser operating at 1064 nm. The study of the effects of free carriers on the refraction and absorption of a delayed probe beam resulted in the determination of the magnitude and sign of these nonlinearities for different Mn concentrations. It was found that at high carrier concentrations the magnitude of the nonlinear refraction coefficient is not constant and decreases with an increase in the electron concentration. The carrier dynamics were studied using forward propagating pulsed probe degenerate four wave mixing. The study was done for a number of different pump beam irradiances. A saturation in the diffraction efficiency was found at higher carrier concentrations. The lifetime of the electrons in the conduction band was determined by monitoring the lifetime of the free carrier absorption.
