Abstract
Vertical-external-cavity surface-emitting lasers (VECSELs) have emerged as an attractive single-frequency laser platform for quantum computing and -sensing applications including optical clocks. VECSELs exhibit a unique combination of features including high-power single-frequency operation, excellent beam, and the ability to cover a broad wavelength range from the ultraviolet to visible and to infrared. Here a compact commercial VECSEL platform with sub-Hz linewidth for optical lattice clocks is presented including recent data for Sr and Yb systems.
