Surface-Emitting Laser Array
High-power, multimode laser diodes are workhorses for many industrial applications. They are used as tools for cutting, welding, sintering and soldering various materials and as pump sources for fiber, disk and solid-state lasers. Many of these applications require fiber-coupled output or a uniformly focused beam.
The task of fiber-coupling and beam-formatting edge emitters is not simple because of large and asymmetric beam divergence. Expensive micro-optic arrays, interleavers and...
