Abstract

Tm3+ and Yb3+ co-doped ZBLAN glass emits strong blue lights when pumped by a 798 nm laser diode which excites Tm3+ ions to 3F4 level. The energy transfer processes between Yb3+ and Tm3+ ions both forward and backward prove to be the origin of upconverted emissions. A brief discussion on this upconversion pump scheme is presented.
