Watt-level fluoroindate based glass fibre laser operating around 3 μm
Watt-level fluoroindate based glass fibre laser operating around 3 μm
Watt-level ∼2.9 μm laser emission in Ho3+/Pr3+ co-doped InF3–ZnF2–BaF2-GaF3-SrF2-PbF2-LiF-YF3-LaF3-NaF fluoroindate glass fibre is demonstrated for the first time. The glass composition is refined to obtain glasses with suitable thermal properties to be drawn into a fibre. Refractive indices are adjusted to operate as core and cladding materials. The maximum output power of 1.35 W with a slope efficiency of 21.14% is achieved at the wavelength of 2864 nm by using a 27 cm length fluoroindate fibre under a 1150 nm Raman laser pumping. The fibre has an attenuation of ∼1 dB/m at 1570 nm, and the effect of fibre length on the slope efficiency is used to optimize the fibre length. The experimental results indicate that fluoroindate glass is a very promising glass material for lasing applications operating within the mid-infrared wavelength range.

Abstract
Watt-level ∼2.9 μm laser emission in Ho3+/Pr3+ co-doped InF3–ZnF2–BaF2-GaF3-SrF2-PbF2-LiF-YF3-LaF3-NaF fluoroindate glass fibre is demonstrated for the first time. The glass composition is refined to obtain glasses with suitable thermal properties to be drawn into a fibre. Refractive indices are adjusted to operate as core and cladding materials. The maximum output power of 1.35 W with a slope efficiency of 21.14% is achieved at the wavelength of 2864 nm by using a 27 cm length fluoroindate fibre under a 1150 nm Raman laser pumping. The fibre has an attenuation of ∼1 dB/m at 1570 nm, and the effect of fibre length on the slope efficiency is used to optimize the fibre length. The experimental results indicate that fluoroindate glass is a very promising glass material for lasing applications operating within the mid-infrared wavelength range.
