Wavelength versatile high power single frequency VECSELs for quantum technology


Vexlum Ltd is a semiconductor laser company located in Tampere, Finland. We capitalize on a comprehensive knowledge in epitaxy, optoelectronics processes, and laser systems engineering. Our vertical external-cavity surface-emitting laser (VECSEL) platform delivers unique benefits in performance, cost, and usability. We specifically address the needs of practical wavelength-versatility laser systems required in quantum technology applications with trapped ions and atoms, for example matching the spectroscopy of Sr (461nm, 689nm), Yb (369nm, 399nm, 556nm), Er (583nm), Be (235nm, 313nm), and Na (589nm). Output powers from 0.5 W to >10 W can be reached at specific wavelengths, while the wavelength coverage generally extends from 350 nm to beyond 2µm enabling a wide range of applications.
