【摘要】 利用两个光纤环镜作为线形腔的端镜,在其中一个环镜中加入腔长可调的F-P腔构成梳状滤波器,从而产生波长间隔可调的多波长激光振荡。实验结果表明,当波长间隔大于1.3nm时,器件可以产生室温下稳定的多波长激光。更多还原

【Abstract】 Using two fiber loop mirrors(FLPs) as end mirrors and inserting a comb-filter with a flexible F-P cavity into one of the FLPs,stable multiwavelength oscillation of ytterbium-doped fiber-line laser has been obtained at room temperature when wavelength spacing is larger than 1.3 nm.The F-P cavity length can be adjusted and the laser wavelength spacings are hence tunable.更多还原
