Abstract
We propose using blue cooperative upconversion of ytterbium ( Yb 3+ ) ions produced by a one-color one-beam pumping scheme for a three-dimensional fluorescence display. The results are presented using a diode laser as a pump source emitting at 973 nm, and the sample used was a multicomponent sol-gel-processed silicaglass (1 mol. % of Yb 3+ ). The maximum absolute blue power emitted was ∼1 μW for an excitation power of ∼900 mW.Keywords
