Abstract
Continuous wave multiple wavelength laser emission was observed in a Tm+3 doped Ta2O5-Al2O3-SiO2 glass fiber with pumping in the 3H6→3F4 transition around 800nm. The oscillation wavelength was within the gain band of 3H4→3H6 with maximum output power of 15 mW and threshold of pump power 20 mW. The variation of lasing wavelengths depending on the cavity length, output coupling ratio is reported.
