OPTICALLY-PUMPED SURFACE-EMITTING SEMICONDUCTOR LASER WITH HEAT-SPREADING COMPOUND MIRROR-STRUCTURE

摘要

A gain-module (12) for use in an OPS -laser includes a multilayer semiconductor gain - structure (14) surmounting a multilayer compound mirror- structure (16). Within the multilayer compound mirror- structure is a relatively thick layer of diamond (20) which serves as a heat - spreader. The compound mirror- structure (16) comprises a partially reflecting DBR (18) and a high reflective DBR (22). The resonator may comprise a nonlinear crystal (32) for SHG. The thickness of the diamond (20) is about 1 mm.
