Monoclinic rare-earth silicates, RE2SiO5, are the promising hosts for Nd3+ doping. We have studied Nd:(Gd,Y)2SiO5, Nd:(Lu,Y)2SiO5 and Nd:Lu2SiO5 crystals for their suitability for ~1.3 μm (4F3/2 → 4I13/2) lasers. The absorption and stimulated-emission cross-section spectra were determined. The continuous-wave laser operation was studied in a compact plano-plano cavity. A b-cut Nd:(Gd,Y)2SiO5 crystal generated up to 0.75 W of linearly polarized emission at 1360.7 nm with a slope efficiency η of 16.9%. For the same crystal operated at the 4F3/2 → 4I11/2 transition, the output power reached 3.84 W at 1077.4 nm with η = 54.5% with a threshold of only 80 mW.
