Tunable wavelength-stabilized mode-locked thulium-doped fiber laser beyond 2000nm

Camille Sophie Brès, Moritz Bartnick, Gayathri Bharathan

We demonstrate operation of a tunable mode-locked thulium-doped fiber laser, based on a wavelength-selective chirped fiber Bragg grating (CFBG). By applying strain to the CFBG, we shift its reflection band and can thereby tune the emission-wavelength of th ...

A tunable femtosecond fiber laser source for multiphoton emission microscopy

Pierre-Marc Jean Marie Dansette

Second harmonic generation microscopy is used to image interfaces or non-centrosymmetric structures and molecules. Two-photon fluorescence microscopy can image molecules within cells without using markers. Thus those technics have lead to advances in our u ...

Multimode optical fibers are the backbone of telecommunication and medical imaging. When light with high intensity travels through a multimode fiber, photons and matter start to interact and propa-gation becomes nonlinear. The nonlinear propagation of ligh ...

System and method for high beam quality pulse generation in mode-locked multimode fiber lasers

Demetri Psaltis, Christophe Moser, Ugur Tegin

A system and method to generate ultrashort high beam quality pulses from spatio- temporally mode-locked multimode fiber laser are described. The invention relies on engineering the intra-cavity pulse propagation in a multimode laser cavity to shape the spa ...

Giant Brillouin amplification in gas using hollow-core waveguides

Luc Thévenaz, Flavien Gyger

We report a strong Brillouin amplification in gas using hollow-core fibers, exceeding by 6 times the gain in solid silica fibers. A novel fiber laser using Brillouin lasing in gas has been demonstrated. ...

Microjoule-level widely tunable gain-switched thuliumdoped fiber laser

Camille Sophie Brès, Svyatoslav Kharitonov

We demonstrate the hybrid-pumped (continuous-wave+pulsed) gain-switched smallcore thulium-doped fiber laser tunable in 1825-2064nm spectral range that delivers 50-300ns pulses with energies up to 12μJ (65μJ of injected pump) reaching performance of larger- ...

OSA Publishing2019

Many molecule bonds have vibration frequencies in the mid-infrared band. Thus, this band is of great interest to molecular spectroscopy, material processing and medical applications. However, many optical materials typically used for laser sources experien ...
