摘要

基于主振荡功率放大器结构的高功率掺Tm

光纤激光器是2 μm波段高功率光纤激光器的主要实现形式，掺Tm

光纤放大器（Thulium-doped fiber amplifier，TDFA）热效应管理的研究对于其输出激光功率的不断提升具有重要意义。本文主要对TDFA热效应管理的泵浦方式优化方面进行理论研究，利用龙格库塔法以及牛顿迭代法求解不同泵浦方式下TDFA的稳态速率方程，并根据热传导方程，模拟掺Tm

光纤（Thulium-doped fiber，TDF）温度沿径向和轴向的分布。结合遗传算法理论，研究了分段泵浦方式，经过参数优化，在功率为5 W的2 020 nm输入信号光、总功率为1 000 W的793 nm激光泵浦、TDF吸收系数为3.1 dB/m条件下，将总长度为11 m的TDF分为2.4，2，2，2，2.6 m的5段进行泵浦，得到放大信号激光输出功率为284.5 W、斜率效率为28.45%、光纤外包层边界最高温度为86.28℃且温度总体分布均匀。与传统前向泵浦、双端泵浦方式下的TDFA相比，其热效应有明显改善。

Abstract

The high-power thulium(Tm

)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

on the basis of the heat conduction equation

the temperature distributions of Tm

doped fiber(Thulium-doped fiber

TDF) along the radial and axial direction are simulated. Combining with the genetic algorithm theory

the segmentally pumping method is studied. Through optimizing of the relative parameters

using a 2 020 nm input signal light with a power of 5 W

a total 793 nm laser pump power of 1 000 W and a TDF with an absorption coefficient of 3.1 dB/m and a total length of 11 m which is divided into 5 segments(2.4

2.6 m)

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.
