The Study of the Interaction of Intense Picosecond Light Pulses with Materials

Abstract

The report contains the summary of the works performed in the entire period of this grant. The two-photon and three-photon photoconductivity effects in various semiconductors were studied. The effect was then applied to measure the ultrashort optical pulses. Two-photon pump GaAs bulk laser action was demonstrated. A theoretical calculation on the optical third harmonic generation with broad band picosecond pulses was made. Finally various aspects of the nonlinear optical interaction at the boundary of nonlinear media were investigated. The data agreed well with Bloembergen and Pershan's theory. The observation of the nonlinear Brewster's angle was reported for the first time in a transparent medium.
