LASER COMPONENTS introduces its coupling unit for CO2 lasers

LASER COMPONENTS introduces its coupling unit for CO2 lasers: They are easily connected to the CO2 laser so that laser beams are coupled with low loss into a hollow-core fiber - the diameter of the laser beam can be up to 5,00 mm. Analyses show very good transmission behavoir for fibers with an inner core diameter of 750 μm and 1000 μm.

Due to its modular flange design, the coupling unit can be connected to any available CO2 laser source. Several adjustment screws make it possible to optimally adjust the laser beam across two rotatory and three translational axes. To connect a fiber, the coupling unit is equipped with an SMA connection. Appropriate hollow core fibers in a rugged metal jacket are available, too. Moreover, they are equipped with a ZnSe window to prevent dirt from entering.

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).
