Fiber laser pump module with high brilliance Jul 16, 2009

It is based on the coupling of several single emitters and achieves an optical output power of 50 watts in continuous mode from a fiber with a core diameter of 105 µm and a numerical aperture of 0.15, thus having an especially high brilliance with a compact design of only 100 mm x 60 mm x 25 mm. The main areas of application of the single emitter fiber-coupling are optical pumping of fiber lasers and direct material processing. This module is characterized by a high level of robustness and easy handling. The cooling of this diode laser module is carried out passively through the base plate. Another feature of this newly developed product is an integrated filter that protects against back reflection from the fiber laser beam.
