This company has developed a solution for forming “square” laser diode light into a homogeneous beam of light of any desired shape. The beam shaper is made of flexible glass fibers and can be coupled directly with the laser diodes. Collimation lenses are no longer necessary.
The beam shaper consists of multi-component glass fibers that have been fused into a rectangular input profile. Sizes of up to 15.0 x 1.0 mm are available. Coupling the laser diodes without fast axis collimation (FAC) lenses improves the overall performance and flexibility of these devices.
The light emitted by the laser diodes can be converted into various shapes and exhibit high laser beam quality. The existing fibers cover a numerical aperture range from 0.4 to 0.8. In addition, transmission of 80% is possible for common light guide lengths of up to 2000 mm.
