Continuous-wave oscillation of a monomode ytterbium-doped fibre laser

Abstract

Laser emission has been observed in a monomode fibre doped with ytterbium. A wide tuning range has been observed, 1.015μm to 1.140μm, when pumped by a dye laser at 840 nm. Diode pumped operation has also been achieved in a cooled fibre.
