Output Characteristics of Heterolasers with a Wide Stripe Contact

Abstract

Output power characteristics of high efficiency quantum-well heterolasers with a wide stripe contact based on the AlGaInAs semiconductor compounds are studied. It is shown that the laser elements can be applied together with focused and collimated optics for different purposes. In particular, the described laser diodes are suitable as optimal sources for the pumping of the YAG: Nd lasers. Improved output power characteristics and parameters of the heterolasers are provided due to more careful producing the supplied contacts and obtaining the homogeneous distribution of the lasing intensity in the p–n junction plane.
