Abstract

Finite-element analysis is used to explore the practicalities and power-scaling potential of quasi-monolithic microchip vertical-external-cavity surface-emitting lasers: thermal lensing and its implications for transverse mode control are emphasised. A comparison is made between the use of sapphire and diamond heat spreaders. The experimental characterisation of an InGaAs/sapphire microchip VECSEL is presented as an exemplar system and the factors affecting slope efficiency, threshold and output power roll-over are examined. By comparing experimental measurements with the finite-element model, the key role of thermal lensing in transverse mode control is demonstrated.
