Fiber-coupled laser diode module JOLD series

Our legacy products: single- or multi-laser-bar fiber coupled modules in a rugged OEM design The advent and fast growth of fiber lasers has lead many diode laser manufacturers to apply single-emitters as the basic building-block for power scaling in fiber-coupled modules, since they enable coupling at high beam quality into 105 µm / NA 0.15 fibers as required for current fiber laser pumping schemes. At Jenoptik we continue to focus single- or multi-laser bar fiber-coupled modules for optical pumping of DPSSL or low-brightness direct-diode laser (DDL) applications in materials processing such as plastic welding. The bulk of our fiber-coupled diode laser modules are passively cooled: i.e. the module is mounted on e.g. tap-water cooled baseplate via thermally conductive foil compatible with 200/ 400 µm core/ NA 0.22 fibers operating up to 100W cw @ 808 and up to 150 W cw @ 940, 980 nm The use of monolithic multi-emitter laser bars as well as monolithic optics (beam-twisters) make bar-based fiber coupled modules the most cost-effective solution for low-brightness DDL applications.
