Title

Picosecond Degenerate Four-Wave Mixing Studies In Znse.

Abstract

The degenerate four-wave-mixing technique has been applied using 30-ps FWHM pulses of 532-nm light output from a frequency-doubled Q-switched and mode-locked Nd:YAG laser. By introducing 700-ps delay stages in each of the three inputs (forward pump, Ef, backward pump, Eb, and probe, Ep) the decay times of the various grating interactions can be determined. The phase conjugate nature of the signal was successfully verified using a phase distorter. The dominant nonlinear mechanism for producing the signal was the nonlinear refraction induced by photoexcitation of electron-hole pairs. Variation of the pump-probe angle allowed determination of both the ambipolar diffusivity and the recombination time, which were found to be strongly density dependent.
