Abstract
To achieve 2μm laser output, 793nm LD face-pumping Tm3+-doped fiber laser was adopted .Double lens coupling system was designed .Cross relaxation of Tm 3+-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.关键词
