Q-switched thulium-doped fiber laser
Optical Engineering, 1993A 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

High Performance Ultrafast Thulium-Doped Fiber Lasers
2019 Conference on Lasers and Electro-Optics Europe & European Quantum Electronics Conference (CLEO/Europe-EQEC), 2019Ultrafast 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 ...

Progress in thulium doped fiber lasers and aplifiers
SPIE Proceedings, 2012We present results on the development of signal sources for the 2000 nm band. The ASE source is presented with a FWHM bandwidth of 70 nm and -20dB bandwidth of 229 nm with an integrated power of 7.5 mW. Narrow band lasers are presented made of a short piece of core-pumped thulium doped fiber and fiber Bragg gratings.

Temperature-dependent cross section spectra for thulium-doped fiber lasers
Optics Letters, 2023An 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.

Thulium-doped ZBLAN blue upconversion fiber laser: theory
Journal of the Optical Society of America B, 1995A theory is presented for thulium-doped ZBLAN fiber amplifiers and lasers that are upconversion pumped by a single source at ∼1150 nm and emit in the blue spectrum at ∼480 nm. The performance of both heavily saturated traveling-wave power amplifiers and laser oscillators is studied with a view to understanding device optimization.
