All-fibre dual-wavelength thulium-doped fibre laser based on spatial filtering effect

All-fibre dual-wavelength thulium-doped fibre laser based on spatial filtering effect

We report a room-temperature all-fibre dual-wavelength thulium-doped fibre laser that operates around 1900 nm and uses a spatial mode-beating filter in a ring configuration. By pumping the gain medium with an 800 nm laser and controlling the phase mismatch at the splicing points of a thulium-doped f...
