高浓度掺铒光纤激光器在工作过程中会产生弛豫振荡，导致输出功率波动和自脉冲。在这项工作中，我们采用了一种新的EDF与高浓度的Er和Al离子，以抑制弛豫振荡，提高激光器的输出功率。结果，输出功率增加了一倍以上，功率波动减少了一半。线宽缩小到4kHz。13 C2 H2稳频铒光纤激光器的频率稳定度在τ = 1 s时达到1.3 × 10-11，在τ = 102 s时达到2.0 × 10-11。τ = 1 s的短期稳定性也得到改善。
An erbium-doped fiber laser with a high Er-ion concentration generally causes output power fluctuation and self-pulsing resulting from relaxation oscillation. In this work, we employed a new EDF with high Er- and Al-ion concentrations in order to suppress the relaxation oscillation and increase the output power of the laser. As a result, the output power was more than doubled and the power fluctuation halved. The linewidth was narrowed to 4kHz. Furthermore the frequency stability of the 13C2H2 frequency-stabilized erbium fiber laser reached as high as 1.3 × 10-11 for τ = 1s and 2.0 × 10-11 for τ = 102s. The short-term stability of τ = 1s was also improved.
