Amplification at 2.3-µm in 1.9-µm thulium-doped silica fiber laser

Year: 2024

Type: article

Abstract: A high-power 1.9-µm Tm3+-doped silica fiber laser generates 7.3-dB of gain at 2.3 µm when cladding- pumped with 207 W of power at 793 nm. We attribute the 2.3-µm gain to the transition 3H4 → 3H5 of Tm3+.
