Emission properties of highly doped Er3+ fluoroaluminate glass

Er3+-doped fluoroaluminate (AYF) glass was compared with fluorozirconate (ZBLAN) and tetraphosphate (PE) glass as a host material for 1.54 micron emission. Experimental results show that the Er3+:AYF glass has a smaller concentration quenching and much stronger intensity for the 1.54 micron emission...

Beschreibung
Zusammenfassung:	Er3+-doped fluoroaluminate (AYF) glass was compared with fluorozirconate (ZBLAN) and tetraphosphate (PE) glass as a host material for 1.54 micron emission. Experimental results show that the Er3+:AYF glass has a smaller concentration quenching and much stronger intensity for the 1.54 micron emission. At high dopant levels, the 1.54 micron emission is twice as strong in Er3+/AYF glass than in ZBLAN glass, and 10 times stronger than in PE glass. 17 refs.
