To achieve efficient all fiber laser at 2μm, a Tm-Ho co-doped single mode fiber was pumped by a dual double-cladding Er-Yb co-doped fiber amplifier. An all fiber ring laser was formed with a 1550nm/2000nm wavelength-division multiplexier and a fiber coupler. When the drive current of 915nm LD was 6.9A, the maximum laser output power was about 57.23mW, the slope efficiency was measured to be about 12% with the linewidth of 4.5nm, the threshold pump power was about 180mW. The experimental results demonstrate that the laser shows high performance and it is prospective in fields of optical fiber sensing and laser medical treatment.
