Abstract

The latest achievements of quantum dot based semiconductor disk lasers are reviewed. Several lasers operating at 1040 nm - 1260 nm were studied. All the structures were grown with molecular beam epitaxy on GaAs substrates. The number of quantum dot layers was varied and the gain was provided either by the ground or the excited state transition of the quantum dots. Frequency doubling of the lasers was demonstrated and the dual-gain laser geometry was found to be practical solution for intracavity frequency conversion. Intracavity heat spreader and thinned device heat management approaches are studied and compared.
