Where to Buy Hollow-core Fibers

Hollow core fibers are a unique solution enabling the delivery of ultrashort laser pulses (with femtosecond, picosecond or nanosecond duration) with extremely low attenuation and nearly no temporal and spectral distortion. The hollow core fibers can be used from the UV up to the mid-infrared.

UltraFast Innovations (UFI) offers hollow-core fibers which are suitable for compressing high-energy ultrashort pulses by nonlinear spectral broadening in a gas within the hollow core. Complete hollow-core fiber compressors are also available.

Our Crystal Fiber portfolio of specialty fibers spans from nonlinear fibers optimized for octave spanning supercontinuum generation, over the World’s largest single mode ytterbium gain fibers for high power lasers and amplifiers, to advanced hollow core fibers guiding the light in air. Our single-mode LMA fibers are also available as patch cords with standard termination in our aeroGUIDE product range. Moreover, we offer the CONNECT broadband fiber delivery system, enabling easy and robust single mode coupling for fiber delivery at any wavelength – with the industry’s highest coupling efficiency.

Guiding Photonics fabricates hollow core fibers with a metallic reflective coating on the inner side of a hollow glass or plastic tube. For infrared transmitting fibers, there is also a dielectric layer with a thickness optimized for a specific wavelength range.
