摘要
对特殊波长掺镱光纤激光器进行了理论和实验研究。根据镱离子的吸收发射特性,对此类激光器中的增益竞争进行了理论分析,指出了抑制寄生振荡的方法。以1018、980、1173nm光纤激光器为例进行了实验研究。分别获得了309、1.05、15.7W的激光输出。
Ytterbium doped fiber lasers of special wavelength are investigated in theory and experiment. The gain competition between signal and amplified spontaneous emission is theoretically investigated based on the absorption and emission characteristics of Yb3+. Available approaches to suppress parasitic oscillation are analyzed. In experiments, 1018, 980, 1173 nm fiber lasers are established, and the maximum output power of the three fiber lasers are 309, 1.05, 15.7 W, respectively.
