2-μm fluorescence and Raman spectra in high and low Al(PO3)3 content fluorophosphates glasses doped with Er-Tm-Ho
Thermal stability and 2-μm fluorescence of high and low Al(PO_3)_3 content of fluorophosphate glasses are investigated.Thermal stability of high Al(PO_3)_3 content of fluorophosphate glass is better than low Al(PO_3)_3 content of fluorophosphate glass.However, 2.04-μm fluorescence intensity of high Al(PO_3)_3 content of fluorophosphate glass is only 48.2, lower than low Al(PO_3)_3 content of fluorophosphate glass.Raman spectroscopy is employed to investigate the difference in thermal stability and 2-μm fluorescence.Moreover, fluorescence peak intensity ratios of 2.04 to 1.81 μm and 2.04 to 1.57 μm are calculated, which indicate that Er-Tm-Ho doped fluorophosphate glasses are suitable materials in 2-μm applications.
