Vertical external cavity surface emitting lasers (VECSELs) have been considered the "ultimate disk-laser" due to their extremely thin active regions and because they take advantage of the high gain found in semiconductor material. This paper discusses power scaling limitations, including heating effects, surface roughness losses, and laterally guided amplified spontaneous emission (ASE).
