Abstract :
In this paper we demonstrate a tunable optically pumped semiconductor vertical external cavity surface emitting lasers (OPS-VECSELs) operating at around 2-mum wavelength range and emitting 1-W output power. Emission was obtained in a nearly diffraction-limited beam with a M2 value below 1.45
