Vertical-Cavity Surface Emitting Laser-Diodes Arrays Expanding the Range of High-Power Laser Systems & Applications BY ARMAND PRUIJMBOOM, ROLF APETZ, RALF CONRADS, CARSTEN DEPPE, GUENTHER DERRA, STEPHAN GRONENBORN, JOHANNA SOPHIE KOLB, HOLGER MOENCH, FELIX OGIEWA, PAVEL PEKARSKI, JENS POLLMANN-RETSCH, ULRICH WEICHMANN, XI GU AND MICHAEL MILLER


Thermal treatment may be by far the most frequent process used in manufacturing, but only at a few places lasers could make an inroad. For thermal treatment, homogeneous illumination of large areas at a lower brightness, and accurate temporal as well as spatial control of the power is required. This is complicated for conventional high-power lasers, while vertical-cavity surface emitting laser-diode (VCSEL)


, their use can be further expanded W/mm2 are achieved, making the VCEL arrays an ideal solution for


many heating applications, ranging from melting and welding of plastics and laminates to curing, drying, and sintering of coatings. A turn-key system concept has been developed allowing fast and easy configuring systems to the specifications of the applications.

capabilities. Because of their fast switching capability and low power dissipation, VCSELs have been widely used for datacom and sensing applications. By forming large-area arrays with hundreds of VCSELs per mm2
