Laser Components also has multi-mode fibers and special fibers, such as, for example, sapphire fibers and hollow-core fibers available. In addition to these fibers, POFs and cables for applications with special requirements are also available.
ndoor and outdoor fiber optic cables are available in different designs. The SI200/230 optical fiber with a numerical aperture of 0.37 is the standard used in fiber optic cables. Depending on the customer’s requirements, other combinations are also available.
Hollow Silica Waveguides are designed to deliver IR power in a flexible and rugged package from below 2.9 µm up to 20 µm, a region where silica fibers are far too lossy for practical operation.
The waveguides consist of a fused silica capillary tube with an optically reflective internal silver halide coating. For protection, the capillary tube is coated with an external jacket of acrylate, which improves the strength and flexibility of the waveguide.
Because typical silica-based fibers heavily absorb light with wavelengths above 2.1 microns, a different technology is required. The Hollow Silica Waveguide (HSW) is a good solution for mid to far infrared applications, such as power delivery for CO2 and Erbium YAG lasers, and spectroscopy making use of the unique hollow structure.
Polymicro Technologies’ waveguides have been optimized for low optical power loss operation at either CO2 (10.6 µm) or Er:YAG (2.94 µm) wavelengths, although relatively low loss operation is possible in the intervening wavelength band. These waveguides are available with core diameters of 300, 500, 750, and 1000 microns. They can also be built into custom assemblies with protective outer jackets and connectors.
