Abstract
We recently demonstrated laser induced cooling in all oxide silica glass [1], a proof of principle of our materials engineering approach. This technique has the potential of significantly impacting silica photonics by not only improving laser cooling with the preferred rare earth ion, Yb3+, but for the first time, also with different rare earths. The higher rare earth concentration possible in silica without affecting its optical properties, indicates that new amplifiers and laser may be possible. This talk will review our engineering perspective to mitigating serious materials shortcoming in silica and elaborate what may be possible for new applications in photonics. 1. J. Thomas, T.
