Progress of turnkey VECSEL systems for quantum technology

Progress of commercial single-frequency VECSELs for quantum technology applications is reviewed. Availability of practical laser systems with specific wavelength matching an atomic transition is instrumental for the quantum technology research experiments and is becoming increasingly important for the upscaling of commercial quantum systems. To this end, we present a versatile commercial single-frequency VECSEL platform operating in the ultraviolet, visible and NIR -spectral ranges. The suitability of the laser systems for a wide variety of quantum information processing tasks, including spectroscopy, photoionization, and laser cooling is demonstrated.
