Thulium Holmium co-doped tunable fiber laser

Abstract

We report a Tm-Ho co-doped fiber laser with continuous tunability between 1965-2120 nm thanks to a rotating diffraction grating in the laser cavity. It delivers an OSNR of over 60 dB at the central wavelength 2060 nm. The output is linearly polarized with a 0.7% RMS instability. This laser is tailored for spectroscopy of Ho-doped materials.
