 Laser-induced cooling in atterbium-doped silica, SiO2, glass with alumina, yttria-co-doping, GYY aluminum, yttrium, atterbium glass, fabricated using the modified chemical vapor deposition MCVD technique was demonstrated. A maximum temperature reduction of minus 0.9 k from room temperature, 296 k, at atmospheric pressure was achieved using only 6.5 W of 1029 nanometers laser radiation. This novel silica glass has a high potential for a vast number of applications in laser cooling such as radiation-balanced amplifiers and high-power lasers including fiber lasers.
