Aluminum hollow core fibers

Hollow glass waveguides coated with a reflective aluminum layer provide an excellent fiber optic delivery solution for ultra-violet (UV) lasers spanning the wavelength range from 100 – 350 nm. For vacuum UV wavelengths the fibers can be purged with an inert gas.

Coupling into aluminum coated hollow fibers is similar to coupling into our Mid-IR fibers, see here for more details. In general, a relatively long focal length lens should be used with the beam focused straight into the fiber.
