Stretched-pulse operation of a thulium-doped fiber laser
Optics Express, 2008 We report on stretched-pulse operation of a thulium-doped fiber laser. The laser generated pulses at a center wavelength of 1974 nm with an energy of 4 nJ that could externally be compressed to a duration of 173 fs.

Evaluation of a novel laser-system operating at 1940 nm for weed control and determining the influence of biological and operational factors. [PDF]
Pest Manag SciThe control efficacy of a novel laser pulse system operating at 1940 nm was tested. The new system allows effective control of young weeds with 1.5 J. Targeting the plant stem is 53‐fold more energy‐efficient than the meristem. Species morphology and beam diameter significantly influence weed control efficacy. Abstract BACKGROUND This study evaluates a

Ultrafast thulium-doped fiber laser mode-locked by antimonides
Optics Express, 2021 We report, for the first time, the nonlinear absorption at the 2 µm waveband of three Sb-related materials including two Sb compounds, GaSb and InSb, and one Sb alloy, Ge8Sb92. These saturable absorbers (SAs) were coated on tapered single mode fibers by the magnetron-sputtering deposition method.
