Absorption and Emission Characteristics of Highly Er3+ Doped Glasses

The spectroscopic properties, concentration quenching and mechanism as a host material for 1. 54 μm emission for Er3+ highly doped fluoroaluminate (AYF), fluorozirconate (ZBLAN ) and phosphate (PE) glasses excitated with a laser diode operating at 0. 80 μm and 0. 98 μm were investigated and compared
