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 ...

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.

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.

High-power thulium-doped fiber laser in an all-fiber configuration

SPIE Proceedings, 2016
High-power Tm-doped fiber lasers are greatly suitable for various applications, such as material processing, medicine, environmental monitoring and topography. In this work we present an all-fiber narrowband CW laser in near fundamental mode operation based on a Tm-doped double-clad active fiber pumped by 793 nm laser diodes with a central wavelength ...

Ultrafast thulium-doped fiber laser mode locked with black phosphorus

Optics Letters, 2015
We report, for the first time to our knowledge, the usage of black phosphorus (BP) as a saturable absorber for the mode locking of a thulium-doped fiber laser. We have experimentally shown that BP exhibits saturable absorption in the 2 μm wavelength range and supports ultrashort pulse generation.

Thulium-doped all-fiber mode-locked laser synchronously pumping by a fiber laser

SPIE Proceedings, 2016
We demonstrate a thulium-doped all fiber actively mode-locked laser by synchronously pumping without electronic modulator. A mode-locked fiber laser operating at 1550 nm based on nonlinear polarization rotation (NPR) is innovatively utilized as the pulsed pump.

All fiber thulium-doped fiber laser pumped Q-switched Ho:YAP laser

SPIE Proceedings, 2017
The high power infrared 2μm lasers have been extensively investigated for a number of commercial, scientific and engineering applications, such as remote chemical sensing, medical diagnostics, eye-safe laser radar, and environmental monitoring. Furthermore, high-power 2μm lasers are effective pump sources of optical parametrical oscillators and optical
