All-fiber 10 W holmium lasers pumped at lambda=1.15 microm.
Three all-fiber Ho-doped lasers emitting in the range of 2050-2100 nm were fabricated. The lasers were pumped by an Yb-doped fiber laser at 1147 nm with a power up to 35 W. For all the lasers tested, the output power was found to be as high as 10 W, the efficiency slope being 30%.
