Paper Abstract

The model of a new type of high-power laser light generators, based on epitaxially and functionally integrated fast highpower current switch and laser heterostructure, the so-called laser-thyristor, has been developed. In this model, the functional characteristics of the laser-thyristor were analyzed by considering the epitaxially integrated structure as an optoelectronic pair constituted by a heterophototransistor and a laser diode. It was demonstrated that the turn-on of lasing fundamentally affects the injection efficiency of the laser-thyristor. The dynamic characteristics of the laser-thyristor were examined by using analytical relations for the optical feedback. It is shown that the impact ionization can substantially raise the build-up rate of the through current across the laser-thyristor structure and, as a result, make shorter the leading edge of a laser pulse. It is demonstrated that the developed dynamic model is in good agreement with experimental results at the maximum blocking voltages.
