Semiconducting laser with reduced heat losses has a semiconducting chip has active layer structured in direction perpendicular to main radiation direction to prevent heating of semiconducting chip by spontaneously emitted radiation

摘要

The semiconducting laser has a semiconducting chip (1) with an active layer (5) and emits radiation in a main radiation direction (6). The active layer is structured in a direction perpendicular to the main radiation direction in order to prevent heating of the semiconducting chip by spontaneously emitted radiation (10). The laser is a disk laser with an external resonator. The active layer has a region (7) for optical pumping by a pumping radiation source (8).
