Abstract

Quantum information processing based on trapped ion technology is one of the leading platforms, heavily relying on a set of single-frequency lasers in its core operations. Narrow linewidth lasers perform atom photoionization, cooling, state-preparation and read-out. In this work we demonstrate in-house designed and fabricated optically pumped semiconductor laser gain mirror comprised of InGaAs quantum wells and GaAs/AlAs distributed Bragg reflector. We demonstrate in-house designed and fabricated single-frequency laser operating at 493 nm for Ba+ cooling. Inherent power scaling potential, efficient intracavity frequency conversion, coupled with sub-MHz linewidth and wide gain tuneability make VECSELs advantageous semiconductor laser platform for various quantum technology applications.
