Abstract
Abstract
Terahertz quantum-cascade (QC) lasers that operate in the vertical-external-cavity-surface-emitting-laser (VECSEL) configuration are enabled by the use of active reflectarray metasurfaces which serve as one mirror in an external cavity. We present the latest developments in THz QC-VECSELs, including watt-level output power in high-quality beam patterns.
