摘　　要：以两台808 nm半导体激光器LD1和LD2为泵浦源,对光纤激光器双端泵浦进行了研究,获得了6.5 W的激光输出。实验分别测出了LD1和LD2半导体激光器单端泵浦和双端泵浦时的输出功率,对双端泵浦输出功率与单端泵浦功率之和进行了比较,利用双端泵浦提高了泵浦效率和输出激光功率。同时测量了输出激光的偏振度,通过计算得到双端泵浦输出激光的偏振度为0.5。The double-end pumped polarization-maintaining fiber laser was studied by using two semiconductor lasers LD1 and LD2.The output powers of the fiber laser were tested by using LD1 and LD2 single-end pumping and double-end pumping.The output power of double-end pumping was compared with the power sum of LD1 and LD2 single-end pumping,which shows that double-end pumping can enhance the pumping efficiency and output power of the fiber laser.The output power of the double-end pumped fiber laser was 6.5 W,and the output polarization degree was 0.5.
