Thulium Doped Fibre Laser based on Theta Cavity Lasing Direction Rectification

Camille Sophie Brès, Svyatoslav Kharitonov

2015

Isolator-free unidirectionalthulium-doped fiber laser

Camille Sophie Brès, Svyatoslav Kharitonov

We report the first demonstration of a unidirectional, isolator-free 2-mmthulium-doped fiber (TDF) laser, relying on the properties of the theta cavity (ring resonator with S-shaped feedback). The core pumped theta cavity TDF laser provides sub-Watt output ...

Kerr nonlinearity of Thulium-doped fiber near 2 um

Ludovic Zulliger, Camille Sophie Brès, Adrien Billat, Svyatoslav Kharitonov, Steevy Joyce Cordette

The nonlinear coefficient and group velocity dispersion of a thulium-doped fiber near 2μm are evaluated via four-wave mixing. Nonlinearity of thulium-doped fiber can be used for the design of doped-fiber lasers in this spectral region. ...

Continuous wave four-wave mixing at 2 micron in Chalcogenide microstructured fiber

Camille Sophie Brès, Adrien Billat, Svyatoslav Kharitonov, Steevy Joyce Cordette, Davide Grassani, Sida Xing

We present the first demonstration of continuous-wave four-wave mixing at 2μm in short chalcogenide microstructured fiber. Idlers over approximately 15nm on anti-Stokes side of the pump were measured for a coupled pump power of 94mW. ...

High Power Sub-Picosecond Pulsed SWIR Source Based on Thulium Assisted Raman Wavelength Shifting

Camille Sophie Brès, Adrien Billat, Svyatoslav Kharitonov, Steevy Joyce Cordette

We demonstrate 1.5W sub-picosecond pulsed source near 2μm. Cavity-less source is based on integrated association of 3rd order Raman wavelength-shifting and thulium amplification. Coherent spectrum of 61.5nm with 49% pump power conversion efficiency is achi ...
