Journal ArticleDOI
High-power widely tunable thulium fiber lasers
Timothy S. McComb,R. Andrew Sims,Christina C. C. Willis,Pankaj Kadwani,Vikas Sudesh,Lawrence Shah,Martin Richardson +6 more
TL;DR: Two different laser configurations for high-power tunable thulium fiber lasers are reported on: one is a single oscillator utilizing a volume Bragg grating for wavelength stabilization; the other is a master oscillator power amplifier system with the oscillator stabilized and made tunable by a diffraction grating.
Journal ArticleDOI
Laser-induced breakdown spectroscopy of copper with a 2 μm thulium fiber laser
TL;DR: The first implementation of a 2 microm thulium fiber laser in a Laser-Induced Breakdown Spectroscopy system with low ablation fluence and 200 ns pulse duration leads to a plasma with neither continuum emission, nor air emission in the near-infrared region.
Journal ArticleDOI
Spectral narrowing and stabilization of thulium fiber lasers using guided-mode resonance filters
R. Andrew Sims,Zachary A. Roth,Christina C. C. Willis,Pankaj Kadwani,Timothy S. McComb,Lawrence Shah,Vikas Sudesh,Menelaos K. Poutous,Eric G. Johnson,Martin Richardson +9 more
TL;DR: guided-mode resonance filters are used as intracavity feedback elements to stabilize and narrow the output spectrum in thulium-doped fiber oscillators operating in the 2 μm wavelength regime, producing linewidths of <700 pm up to 10 W power levels.
Journal ArticleDOI
Integrated Tm:fiber MOPA with polarized output and narrow linewidth with 100 W average power
Lawrence Shah,R. Andrew Sims,Pankaj Kadwani,Christina C. C. Willis,Joshua B. Bradford,Aaron J. Pung,Menelaos K. Poutous,Eric G. Johnson,Martin Richardson +8 more
TL;DR: A Tm:fiber master oscillator power amplifier (MOPA) system producing 109 W CW output power, with >15 dB polarization extinction ratio, sub-nm spectral linewidth, and M2 <1.25, is reported on.
Proceedings ArticleDOI
High-energy Q-switched Tm3+-doped polarization maintaining silica fiber laser
Christina C. C. Willis,Lawrence Shah,Matthieu Baudelet,Pankaj Kadwani,Timothy S. McComb,R. Andrews Sims,Vikas Sudesh,Martin Richardson +7 more
TL;DR: In this article, the authors report the performance of an actively Q-switched Tm fiber laser system with a blazed reflection grating and a volume Bragg grating.
