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.

Ultra-short wavelength operation of thulium-doped fiber amplifiers and lasers [PDF]
Optics Express, 2019 We fabricate and characterize a germanium/thulium (Ge/Tm) co-doped silica fiber in order to enhance the gain at the short wavelength edge of the thulium emission band (i.e. 1620-1660 nm). The Ge/Tm doped fiber shows an intrinsic blue-shifted absorption/emission cross-section compared to aluminum/thulium (Al/Tm) co-doped fiber, which greatly improves ...

Temperature investigation of low SWaP thulium-doped fiber lasers
Optics ExpressWe investigate the temperature dependence of an in-band core-pumped thulium-doped fiber laser with a low SWaP (size, weight, and power) architecture. The temperature investigation is carried out both experimentally and numerically by a simulation model.

Thulium-doped Fiber Amplifier for Optical Communications at 2µm [PDF]
Optical Fiber Communication Conference/National Fiber Optic Engineers Conference 2013, 2013 We report the first experimental realization and detailed characterization of thulium doped fiber amplifiers (TDFAs) specifically designed for optical communications providing high gain (>35 dB), noise figure as low as 5 dB, and over 100 nm wide bandwidth around 2 µm. A maximum saturated output power of 1.2 W was achieved with a slope efficiency of 50%.
