Abstract (en)
[origin: WO2010026309A1] The invention relates to a laser device (1) having a fibre emitting a single-mode transverse radiation controlled at a given wavelength, which comprises: at least one laser diode (2) capable of emitting a pump wave and a sheathed amplifying optic-fibre segment (6) having two ends, the amplifying optic fibre (2) including a core and a pumping sheath, the fibre being doped with a rare-earth dopant, characterised in that the core of the fibre has a diameter of between 12 µm and 200 µm, and in that the device (1) includes: a coupling means (4) for coupling the pump wave in the pumping sheath to at least one end of the fibre, and a resonator capable of re-injecting a laser beam at the given wavelength at the two ends of said segment (6), said resonator including an intra-cavity wavelength selective means (5, 13) capable of interaction with the injection means (4) so as to perform a filtration on the given wavelength and re-inject into the fibre (6) the pump wave which has not been absorbed after passing in the fibre (6).
