Vertical external cavity surface emitting lasers (VECSELs) have captured the interest of high-brightness semiconductor
researchers, primarily due to their simplicity in design, power scalability, and "open cavity architecture,"
wherein it is simple to integrate nonlinear elements into the cavity. Through direct emission and indirect
(frequency-converted) means, wavelengths from the UV through to the mid-wave infrared regimes have been
demonstrated, increasing the suitability of the VECSEL platform for multiple applications. This presentation
outlines recent progress in VECSELs, measurements, novel cavities, and potential applications for these lasers.
