VEXLUM provides high-power and low-noise laser systems based on vertical-external-cavity surface-emitting laser (VECSEL) technology. Capitalizing from in-house epitaxy of semiconductor gain materials, advanced cleanroom chip processing, and laser engineering, Vexlum lasers provide the broadest coverage of wavelengths from ultraviolet to visible and to near infrared. Vexlum VECSELs have unique benefits in terms usability and cost; namely robust versatile laser design and lowest SWaP-C parameter for watt-level visible single-frequency lasers. These features are instrumental for research and for industrial scaling of quantum technology applications. Vexlum laser platform is currently advancing towards even more compact and modular industrial form factor to enable industrial deployment of quantum technologies.
Role within PASQuanS 2
Reliable high-power and low-noise lasers are required at several wavelengths for the control of the trapping potentials, and will be developed during PASQuanS2.1 in conjunction with industry technology partners. These lasers will advance local control methods, also dynamical ones, beyond the state of the art to allow for enhanced local programmability of the simulators. The data rate of these simulators is also dependent on the available laser power. With the availability of higher power levels new cooling methods become available, which have the potential to speed-up the simulator run-time by an order of magnitude. VEXLUM will develop a compact VECSEL-based system at 973nm +/- 0.5nm, with 10W output for Rydberg atom control and with fast feedback paths to lock the frequency to a high finesse cavity for low phase noise.
