A patchcord developed by Laser Components allows users to transmit CO2 laser light to the desired location. The laser light is coupled into the fibre with a suitable fibre coupling unit.
The main part of the patchcord is a hollow silica waveguide with a core diameter of 500µm, 750µm or 1,000µm. The fibre is protected by a metal tube which limits the bending radius and protects the fibre against breakage. The two SMA connectors on the in-coupling and out-coupling ends include zinc selenide (ZnSe) windows to protect the hollow silica waveguide against dust and moisture. The patchcord is available with a fibre that can also transmit a pilot beam.
