双端泵浦保偏光纤激光器

摘要

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 doubleend pumped fiber laser was 6.5 W, and the output polarization degree was 0.5.%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.
