Optically pumped semiconductor laser device

摘要

An optically pumped semiconductor laser device having a surface-emitting vertical emission region ( 1 ) and at least one monolithically integrated pump radiation source ( 2 ) for optically pumping the vertical emission region ( 1 ). The semiconductor laser device is distinguished by the fact that the pump radiation enters the vertical emission region ( 1 ) in the form of partial bundles of rays of radiation with different radiation directions so that the pump radiation and the fundamental mode of the vertical emission region ( 1 ) have an overlap which is suitable for the excitation of this fundamental mode. This device is based on the fact that the fundamental mode of the vertical emission region ( 1 ) is preferably excited when the spatial intensity distribution of the pump radiation matches the profile of the fundamental mode.
