Q-switched thulium-doped fiber laser

Optical Engineering, 1993
A tunable Q-switched thulium-doped single-mode silica fiber laser is presented for the first time. Its performance is analyzed as a function of pulse repetition rate and pumping power. The optimization of laser parameters resulted in 4 W/1 30 ns, 1 .92-jrm wavelength pulses generated at a 4-kHz repetition rate. From the measured values of small- signal

Mode-locked tunable thulium-doped fiber laser

SPIE Proceedings, 2017
We report on an all-fiber, actively mode-locked, tunable, Thulium-doped, fiber laser based on a 20-GHz bandwidth electro-optic intensity modulator (EOM) and a voltage driven 2-μm, intra-cavity, fiber-coupled, Fabry-Perot tunable filter (FFP-TF). The repetition rate of output pulses was 47 MHz and the shortest measured output pulse width was 445 ps.

The slope efficiency of 2μm thulium doped fiber laser

SPIE Proceedings, 2010
In order to obtain high slope efficiency of 2 μm laser output, it is essential to design operating parameters of fiber laser prior to the experiment. Based on the rate equations, the pump and signal power equations of thulium doped fiber laser have been built.

Switchable multiwavelength thulium-doped fiber ring lasers

Optical Engineering, 2013
Two kinds of thulium-doped fiber ring lasers based on a spatial mode beating filter and comb filtering effect are presented and experimen- tally demonstrated, which all show multiwavelength laser spectrum around 2 μm. In the implementation of the first type of experiment configuration by the use of a piece of multimode fiber (MMF) as a spatial mode ...

Temperature-dependent cross section spectra for thulium-doped fiber lasers

Optics Letters, 2023
An investigation on the temperature dependence of spectroscopic parameters of trivalent thulium ions is important for the design of high-power, thulium-doped fiber lasers and amplifiers. In this Letter, the thulium absorption/emission cross sections are determined in the spectral range 700–2200 nm and in the temperature range from −196°C to 300°C.

High Performance Ultrafast Thulium-Doped Fiber Lasers

2019 Conference on Lasers and Electro-Optics Europe & European Quantum Electronics Conference (CLEO/Europe-EQEC), 2019
Ultrafast lasers that deliver intense femtosecond pulses at carrier wavelengths beyond the well-established emission bands of Yb- or Ti:Sa-based sources have become extremely popular drivers for scientific applications. It is widely known that the long wavelength is a key property to enable new strong-field experiments or to significantly improve ...

All-fiber thulium-doped fiber ring laser with in-band pumping

Workshop on Recent Advances in Photonics (WRAP), 2013
A continuous-wave thulium-doped fiber laser at around 1.9 μm has been demonstrated in all-fiber ring configuration. Single-wavelength and multi-wavelength lasing has been observed at different lengths of the doped fiber in the filterless configuration.
