FIBRE OPTIQUE POUR AMPLIFICATION OU POUR EMISSION LASER

The amplifier has sections (1, 2, 3, 4, 5), each provided with different maximum indices and radii. The indices and radii are determined such that an optic fiber presents a multi-mode core extending from the center, at a pumping wavelength signal. The section (2) presents a pattern in decreasing gra...

Zusammenfassung:	The amplifier has sections (1, 2, 3, 4, 5), each provided with different maximum indices and radii. The indices and radii are determined such that an optic fiber presents a multi-mode core extending from the center, at a pumping wavelength signal. The section (2) presents a pattern in decreasing gradient so as to re-center the light energy, from multimode, guided at a pumping wavelength.
