Nonlinear Optical Interactions in Semiconductors
Abstract
The optical pumping technique in GaAs has led to the development of a novel and highly sensitive optical temperature sensor. Experiment were completed on two-photon optical pumping pumping ZnO. An external cavity semiconductor laser involving ZnO as a gain medium was demonstrated under two-photon excitation. This laser should have major impact on the development of tunable blue-green radiation for submarine communication. Two large laser systems were received along with a variety of test and measurement equipment. These lasers were used to explore elementary excitation in optical thin film layers of semiconductors. Also, demonstrated was the feasibility of room temperature operation of a tunable coherent source involving multiple quantum well material. The construction was completed of a simple remote (non-contact) temperature sensor to directly measure heat buildup in semiconductor materials as a result of high power optical laser systems, is in the planning stage. Attempts are focused on observing a number of new optical effects including nonlinear absorption and transmission phenomena, enhanced spontaneous and stimulated light scattering processes, etc. The construction of an external cavity semiconductor laser has been completed. This will allow us to undertake a careful study of multi-photon optical pumping in semiconductors to generate IR radiation and a variety of studies involving narrow-gap semiconducting compounds.
