2-\mu m fluorescence and Raman spectra in high and low Al(PO3)3 content fluorophosphate glasses doped with Er-Tm-Ho
Thermal stability and 2-\mu m fluorescence of high and low Al(PO<sub>3</sub>)<sub>3</sub> content of fluorophosphate glasses are investigated. Thermal stability of high Al(PO<sub>3</sub>)<sub>3</sub> content of fluorophosphate glass is better than low Al(PO<sub>3</sub>)<sub>3</sub> content of fluorophosphate glass. However, 2.04-\mu m fluorescence intensity of high Al(PO<sub>3</sub>)<sub>3</sub> content of fluorophosphate glass is only 48.2, lower than low Al(PO<sub>3</sub>)<sub>3</sub> content of fluorophosphate glass. Raman spectroscopy is employed to investigate the difference in thermal stability and 2-\mu m fluorescence. Moreover, fluorescence peak intensity ratios of 2.04 to 1.81 \mu m and 2.04 to 1.57 \mu m are calculated, which indicate that Er-Tm-Ho doped fluorophosphate glasses are suitable materials in 2-\mu m applications.
