The UM7800/100/20 series offers a kink free optical power of 7.8 W from a 100 µm N.A. 0.22 fiber at 808 nm and therefore a globally unique brightness for this kind of laser. This performance makes them a valuable tool for the highly efficient pumping of Nd⁺ doped solid state lasers. Further important applications are micro material processing with exceptional power densities, illumination and medical lasers. The unique brightness is achieved by transforming the asymmetric radiation from the laser diode into a symmetrical beam using a patented micro optics. This beam can be coupled into a fiber with a very small core and numerical aperture with a high efficiency. The available power of the system is well adapted to different processing tasks like: · microsoldering · microwelding of polymers and · marking of work pieces
