Optical and laser properties of Tm3+-doped air-cladding fiber fabricated by plasma non-chemical vapor deposition

摘要

Tm3+/Al3+ co-doped silica glass with the composition of 0.08 Tm2O3-0.8 Al2O3-99.12 SiO2 (mol%) is prepared by combining the high-temperature plasma furnace sintering technology and the dried RE-doped granulates. Using the prepared Tm3+/Al3+ co-doped silica glass as the fiber core, the Tm3+/Al3+ co-doped air-cladding fiber is fabricated by the stack-and-draw technology. Optical and laser properties of Tm3+/Al3+ co-doped air-cladding fiber are studied. The experimental results show that the Tm3+/Al3+ co-doped air-cladding fiber can be used as the potential material for the high-power fiber laser operating at 2 mu m.
