Emission properties of highly doped Er3+ fluoroaluminate glass

Abstract Er 3+ -doped fluoroaluminate (AYF) glass was compared with fluorozirconate (ZBLAN) and tetraphosphate (PE) glass as a host material for 1.54-μm emission. Experimental results show that the Er 3+ :AYF glass has a smaller concentration quenching and much stronger intensity for the 1.54-μm emission. In high dopant, the 1.54-μm emission is two times stronger in Er 3+ /AYF glass than in ZBLAN glass, and 10 times stronger than in PE glass.
