Hollow optical fibers for UV light

If you want to send light on a trip through optical fibers — with as little loss as possible, you should opt for infrared light, as is the case, for example, in the telecommunication networks worldwide. For certain applications, such as spectroscopic investigations on ions or atoms, however, (laser) light in the ultraviolet range is required. But this type of light would quickly damage conventional optical fibers. Researchers have now tested a new type of optical fiber with a hollow core and have found out that this type of optical fiber was able to guide UV laser light without being damaged and with acceptable loss.
