| 摘 要： | 基于半导体光放大器(SOA)的锁模光纤环行激光器因其能得到高质量、高重复率的光脉冲而受到人们的广泛关注。计及SOA端面剩余反射率,建立了基于SOA的谐波锁模光纤环行激光器的理论模型。利用该模型研究了SOA的端面剩余反射率对输出脉冲的波形、峰值功率及其脉冲宽度的影响。结果表明,SOA的端面剩余反射率对锁模脉冲影响较大;随着端面剩余反射率的增大,峰值功率逐渐增加,脉冲宽度逐渐变宽。

| Abstract: | Actively mode-locked fiber lasers based on the semiconductor optical amplifier(SOA),which are capable of generating ultra-short pulse train with high quality and high repetition rates,have received considerable attention.After considering the facet reflectively of the SOA,a theoretical model of the harmonic mode-locked fiber ring laser based on SOA is established.Based on this model,the influence of the facet residual reflectivity on the shape,peak power,and pulse width of the pulse output from the harmonic mode-locked fiber ring laser is studied.The results show the residual facet reflectivity of the SOA affects seriously the shape of the mode-locked pulse.With the increase of the facet reflectively of the SOA,the peak power of the mode-locked pulse will be increased and the mode-locked pulse will be broaden. |
