FIBRE LASER

摘要

The invention relates to a fibre laser which is pumped by a diode laser and stabilised in terms of power, said fibre laser consisting of a doped fibre (20), a pump source (10), and entrance and exit resonator units. Said fibre laser is characterised in that the entrance resonator unit (14) and/or the exit resonator unit (26) are separated from the end surfaces (18, 22) of the fibre by adjustable gaps (16, 24) of up to 20 µm. Controllable adjustment of the size of the gaps enables light to be emitted on a plurality of changeable or simultaneously excited emission wavelengths in the visible and near-infrared region.
