Grating-free nth order cascaded Raman fibre lasers using highly Ge-doped low loss fibre.
Pumped by a narrow band Nd(3+)-doped fibre laser, a grating-free three-wavelength Raman fibre laser has been demonstrated. More than 1.3W output power at the third Stokes line of 1230 nm, a bandwidth of 1.8nm and a slope efficiency of ~28% was measured. A four-wavelength Raman fibre laser was also demonstrated using a different resonator that consisted of a 4% fibre end reflector, a dielectric ...
متن کاملChiral Optical Fibre and Grating
The focal purpose of this thesis is to study chirality specifically in telecommunications area, through the pure chiral fibres (optical fibres constituted by chiral material) and chiral fibre grating (twisted optical fibre), analysing also its behaviour and applications. Nevertheless we shall also address this theme from an economical perspective. The study begins by giving a brief introduction...

متن کاملAssessment of Ge-doped optical fibre as a TL-mode detector
This study analyses the thermally stimulated luminescence or thermoluminescence (TL) glow curve between 300 and 773 K of germanium-doped silica optical fibre. A main glow peak at 530 K with a characteristic spectral emission centred at 400 nm is found. Both features are particularly suitable for dosimetry. Thus, an investigation by the TL technique of some first clinically relevant features of ...
