Stable Multi-Wavelength Thulium-Doped Fiber Laser With Two Cascaded Single-Mode-Four-Mode-Single-Mode Fiber Interferometers

IEEE Access, 2021
We propose and experimentally demonstrate a multi-wavelength thulium-doped fiber laser using two cascaded single-mode-four-mode-single-mode (SFS) fiber interferometers and a 150-m-long highly nonlinear fiber.

Continuous wave and modelocked femtosecond novel bulk glass lasers operating around 2000 nm

, 2011
This thesis reports on the development of glass-based femtosecond laser sources around 2 µm wavelength. In order to be able to produce 2 µm radiation the dopants used were trivalent Thulium (Tm³⁺) and trivalent Holmium (Ho³⁺) that could be optically ...

Ultrashort pulse formation from a thulium-doped fiber laser: Self-characterization and mapping

, 2021
We have performed an automatic characterization of a mode-locked thulium-doped fiber laser in soliton regime based on a versatile scheme of nonlinear polarization rotation (NPR) mode-locking.
