Design of High-Power Electrically-Pumped VECSELs for the 3–4 μm Wavelength Range

Abstract

We report the design of electrically-pumped high-power vertical-external-cavity surface-emitting lasers emitting at the mid-wave infrared wavelength regime. The device is designed with a monolithic configuration that can provide multiwatts of continuous-wave output power in a single transverse mode with an excellent beam quality.
