The continuous pursuit for emitters with higher power, good beam quality and wavelength tunability has led to the development of devices at the frontier between solid-state and semiconductor laser technologies. Optically-pumped semiconductor disk lasers, also called vertical-external-cavity surface-emitting lasers (VECSELs), offer many advantages over standard semiconductor lasers such as high brightness, ultra-short pulse generation, single-frequency operation, etc. However, the significant long growth time and complexity of the Bragg reflector (DBR), as well as its high thermal resistance, hinder their full exploitation. In this presentation, we show the recent achievements and development of new semiconductor disk laser platforms in the 1-1.2 µm range using GaInAs MQWs gain structures towards the realization of continuous-wave high-power regimes.
Davide Priante received his BSc degree in Material Science Engineering from the University of Padova, Italy, in 2013. He then moved to Saudi Arabia, at King Abdullah University of Science and Technology (KAUST), to pursue his MSc and PhD degrees in Electrical Engineering with a thesis on nanostructured AlGaN ultraviolet light-emitting diodes. He is currently a postdoctoral fellow in Mansoor Sheik-Bahae's group working on novel semiconductor disk lasers for sodium guide star applications.
