Abstract:

In this Phase I SBIR project, Physical Optics Corporation POC experimentally demonstrated an innovative concept of a nonimaging beam combiner-concentrator NIBCC. POC designed and fabricated the NIBCC prototype, which consists of three laser diodes coupled to optical fibers, three GRIN lens objectives for focusing light into the NIBCC focal point, a mechanical assembly for aligning the focusing device, and the beam combiner. The designed divergence of the outgoing beam is - 3 minutes, which provides a 10 m light spot at a 5 km distance. In the NIBCC prototype, we achieved - 5.5 minutes divergence. The excess divergence in the NIBCC prototype is due to several factors that will be eliminated during Phase II. The prototype built during Phase I proved the potential of the proposed device and created a foundation for its further development to achieve the required characteristics.
