Abstract

A vertical external-cavity surface-emitting laser is presented that emits 2.6 W of continuous-wave radiation centered at 1015 nm. The emission consists of a two-color spectrum with a difference frequency in the terahertz regime. The stability of the dual-wavelength operation is studied, utilizing a cavity design with multiple folds onto the gain medium. It is shown that spatial hole burning effects significantly help to improve the gain competition dynamics of the emitted wavelengths.
