An ultrahigh-brightness single-emitter-based pump block fiber-coupled laser system announced by Visotek Inc. delivers 350 W from a 200-μm fiber with a 0.2 NA. It incorporates Bookham Inc. high-power single-emitter laser diodes that produce >10-W operational light output power. The optical design of the pump block was developed by the Fraunhofer Center for Laser Technology. The system eliminates beam-shaping optics to enable high coupling efficiencies and compact dimensions. It can serve as the pump unit for next-generation fiber laser systems as well as for direct applications.
