We fabricate the Tm-doped double cladding silica fiber by using the vapor-solution hybrid-doping method,then build up an all-fiber Tm-doped fiber laser which can provide the output power of up to 121 W,corresponding to a slope efficiency of 51%and an optical-optical efficiency of 48%.By using the domestic Tm-doped fiber,it is the first time a hundred-watt level output at 1915 nm has been achieved,to the best of our knowledge.The thermal effect of Tm-doped fiber laser is also analyzed.
