Visotek/Bookham team on Ultra-High-Brightness pump block

Visotek has selected Bookham as the diode laser supplier for its Ultra-High-Brightness single-emitter based pump block. The fiber-coupled laser system delivers 350 watts from a 200 um fiber at 0.2NA.

The fiber coupled laser system incorporates the latest generation of the Bookham high-power single-emitter diode lasers capable of in excess of 10W operational light output power. The optical design of the pump block was developed by the U.S. based Fraunhofer Center for Laser Technology. The system eliminates beam shaping optics, enabling exceptional coupling efficiencies and compact dimensions at high power levels. 350W fiber coupled power can be achieved at moderate output powers from the laser chip, which offers improved system lifetime.
