Abstract
Laser cooling of ytterbium doped silica glass fibers by anti-Stokes fluorescence to 18 Kelvin below room temperature has been observed. This milestone achievement breaks the record for cooling a silica fiber by two orders of magnitude. Our new record demonstrates the viability of using silica as a material for radiation-balanced fibers and amplifiers. Numerical simulations using the parameters of the experimentally investigated fiber indicate the potential of self-cooled lasers outputting multiple watts.
