Osram Opto Semiconductors has introduced the SPL BF series mini laser bars, which operate from 910 to 1020 nm for pumping fiber lasers and for direct micromaterials processing such as marking and microwelding. The light beam leaves the laser aperture at a defined angle and can be coupled into a 200-μm fiber core diameter with a restricted acceptance angle and a numerical aperture of 0.22. The bars’ very large optical cavity epitaxial structure and proprietary mirror coating technology produce high brilliance. Fill factor is 10%, output is 8 W per emitter at an emitter width of 100 μm, and slow-axis divergence is <7°.
