Abstract

Membrane-external-cavity surface-emitting lasers (MECSELs) were originally demonstrated by Prof. Mansoor Sheik-Bahae’s group at the University of New Mexico (UNM) in 2015. MECSELs consist of an epitaxial active region combined with at least one transparent heatspreader, typically SiC or diamond, employing external cavity mirrors for feedback. The standalone gain element allows for significant flexibility in emission wavelength and is amenable to enhanced power scaling via optimized thermal management. In an extremely fruitful collaboration with UNM beginning in 2017, we progressed from serially-produced chip-scale prototypes, to 4” wafer-scale manufacturing of double-bonded (SiC/epi/SiC) devices capable of single-mode frequency-doubled output powers in excess of 10 W. Leveraging this unique architecture, we see a bright future ahead for multi-Watt-output optically-pumped semiconductor laser systems emitting throughout the visible and infrared spectral regions.
