Abstract
A host material for Tm -doping is provided. The host material is a fluorophosphate glass having a non-zero concentration of Tm , cation elements that include at least an alkaline earth, phosphorus, and aluminum, and anion elements that include oxygen (O) and fluorine (F). The fluorine(F)/oxygen (O) ratio (F/(F+O)) for the fluorophosphate glass of the embodiments of the present invention can be in the range of about 0.5 to about 0.85. The fluorophosphate glass further can have an alkali metal concentration of 10 mole % or less to improve durability. The Tm-doped fluorophosphate glass can be incorporated into an amplifier or laser utilized in the 14xx nm wavelength region.
