To achieve 2μm laser output, 793nm LD face-pumping Tm3+-doped fiber laser was adopted. Double lens coupling system was designed. Cross relaxation of Tm3+-doped fiber laser and thermal effect were analyzed, and then the related experiments were carried out. The results show that coupling efficiency of coupling system is 84%. When the pump power is 70W, the output power is 34W with slop efficiency of 59%, central wavelength of 2001.2nm and M2 of less than 1.2. The results are helpful to design Tm3+-doped fiber lasers.
