High-Brightness Diode Lasers for Blue-Green Applications

Abstract

Experimental investigations of the physics of self pumped photo- refractive phase-conjugators are performed. Particular emphasis is placed on studying the properties of backward stimulated photo-refractive scattering (BSPS) conjugators in BaTiO3, and on attempts to demonstrate self-pumped phase- conjugation in GaAs. The phase-conjugate reflectivity of BSPS conjugations in BaTiO3 is shown to be significantly enhanced by the use of feedback. An experimental comparison of three distinctly different geometries for feedback- enhanced backward stimulated photorefractive scattering (FE-BSPS) is made. In one case, the feedback is found to stabilize the reflectivity, while in the other case, it greatly enhances the peak reflectivity. Barium titanates, Gallium arsenides, Diode lasers.
