)doped fiber laser(TDFL) based on the structure of master oscillator power-amplifier is the main type of 2 μm band high-power fiber lasers. Study on thermal effect management of the thulium doped fiber amplifier(TDFA) stage means a lot to the continuously power-scaling of the TDFL. This paper mainly focuses on the theoretical research on the optimization of the pumping method of TDFA for thermal effect management. We use the Runge-Kutta method and Newton iteration method to solve the steady-state rate equation of TDFA under different pumping methods. And

we obtained an amplified signal laser with an output power of 284.5 W and a slope efficiency of 28.45%
and the maximum temperature at the outer cladding boundary of the TDF is only 86.28 ℃ with a uniform temperature distribution along the whole fiber. Compared with a TDFA using traditional forward pumping or dual-end pumping mode
the thermal effect has been significantly improved.
