Jenoptik's Lasers and Material Processing division has launched JOLD-50-FC-11, a fibre-coupled diode laser module. It is based on the coupling of several single emitters and achieves an optical output power of 50W in continuous mode from a fibre with a core diameter of 105μm and a numerical aperture of 0.15, thus having an especially high brilliance.

The main areas of application are optical pumping of fibre lasers and direct material processing. The module is characterised by a high level of robustness and easy handling. The cooling of the diode laser module is carried out passively through the base plate.

Another feature of the product is an integrated filter that protects against back reflection from the fibre laser beam. The diode laser module has a compact design of only 100 x 60 x 25mm and a low operating current of less than 10 amps.
