In order to study thermal effects of high power double clad fiber laser,the thermal distribution of Yb3+-doped double clad fiber laser is derived and calculated.It is shown that absorption coefficient and clad radius of fiber,heat transfer coefficient and pumping method can affect temperature distribution.Conclusions are useful for designing kW level fiber lasers.
