OPTICALLY-PUMPED EXTERNAL-CAVITY SURFACE-EMITTING SEMICONDUCTOR LASERS WITH FRONT-COOLED GAIN-STRUCTURES
A semiconductor gain-structure functions as a gain-element in a laser-resonator. The gain-structure is bonded to a diamond heat-spreader that is peripherally cooled by a heat-sink configured to allow access to the gain-structure by laser-radiation circulating in the laser-resonator. In one example,...

| Zusammenfassung: | A semiconductor gain-structure functions as a gain-element in a laser-resonator. The gain-structure is bonded to a diamond heat-spreader that is peripherally cooled by a heat-sink configured to allow access to the gain-structure by laser-radiation circulating in the laser-resonator. In one example, the gain-structure is used as a transmissive gain-structure in a traveling-wave ring-resonator. In another example, the gain-structure surmounts a mirror-structure which functions as an end-mirror of a standing-wave laser-resonator. |
