Abstract

Laser generated blue light can be exploited in many fields (welding of metals, entertainment, biomedical…). Several of these applications require an autonomous and compact laser source, with emitted power in the order of tens of watts, keeping low cost-per-watt and enabling high-volume production. Present paper reports a new blue laser multi-emitter source, relying on proprietary low-SWaP (Size Weight and Power consumption) architecture, and integrating on the same package the electronics to control, monitor, perform automatic measurements and satisfying safety requirements. The dedicated electronics is designed to drive the high voltage required by the GaN semiconductor diodes connected in series. This integrated electronic multi-emitter demonstrated emitted power of 100 W on 105 μm core fiber, together with a Numerical Aperture (N.A.) of 0.16.
