The paper deals with optimization of fibre laser based on experimental erbium- and ytterbium-doped fibre with simple double-clad structure pumped by multimode laser diode in 980 nm band. Fibre preparation and its characteristics are described. Different resonator configurations were investigated for the laser optimization, including high reflectivity fibre loop mirror. Experimental optimization ofthe pump wavelength, fibre length and output coupler ratio were carried out. The results obtained under the cladding pumping are compared with those measured with a fibre ring laser containing the same fibre single-mode pumped at 1060 nm.
