Compared with traditional optical fiber lasers,double-clad photonic crystal fiber (PCF) lasers have larger surfacearea-to-volume ratios.With an increase of output power,thermal effects may severely restrict output pow...
We report on a quasi-three-level large-mode-area double-clad Yb-doped fiber laser that adopts a linear cavity consisting of a 0°fiber end and a cavity mirror.Two kinds of Yb−doped photonic crystal fiber(PCF)with diff...

We report a thulium-doped silica fibre laser that generates a maximum cw output power of 6 W in a 2 μm wavelength range when cladding-pumped by a laser diode (LD) operating at approximately 791 nm at room temperatu...
Using a Tm^3+-doped double-cladding silica fibre, we produce a maximum cw 2.2 W output at approximately 2μm. The highest achieved slope efficiency is 29.3% respect to the launched pump power. The lowest threshold is...
