Abstract

We report a terahertz quantum-cascade vertical-external-cavity surface-emitting laser (QC-VECSEL) emitting around 1.9 THz with up to 10% continuous fractional frequency tuning of a single laser mode. The device shows lasing operation in pulsed mode up to 102K in a high-quality beam, with the maximum output power of 37mW and slope efficiency of 295mW/A at 77 K. Challenges for up-scaling the operating wavelength in QC metasurface VECSELs are identified.
