FiberKey®
Fiber couplers are used to couple laser beams into an optical fiber. The optics in fiber couplers can be optimally positioned along the x-axis, y-axis, and z-axis using adjustable screws to couple the maximum amount of laser power into an optical fiber.
The optics can also be tilted slightly. The fiber couplers are available for standard quartz fibers and hollow-core fibers (for Er:YAG and CO2).
