Abstract

This paper describes the family of blue laser modules developed in Convergent Photonics, relying on a proprietary architecture of spatial and polarization multiplexing and making use of the same platform and assembly lines of similar 9xx nm laser diode multi-emitters. This proprietary technology leads to high emitted power, together with unprecedented - for blue laser sources - low SWaP (Size Weight and Power consumption) and high brightness, suitable for a cost reduction over high volume productions. Present realization is an extremely compact (53 mm × 138 mm × 14.6 mm) laser source, based on a spatial and polarization multiplexing of 20 diodes, with a 114 um core / 125 um cladding multimode fiber output. Prototypes demonstrated power in excess of 100 W at 450 nm, with 95 % of emitted power filling only 0.15 numerical aperture (N.A.).
