本文报道了一种超长腔、全光纤、全正色散掺Yb光纤激光器，该激光器由半导体可饱和吸收镜（SESAM）被动锁模。在没有任何离散色散补偿元件或传统的光谱滤波器的情况下，SESAM与强啁啾脉冲和非线性引起的光谱展宽一起工作，以执行滤波等效功能，从而稳定锁模。激光器产生4.3 nJ的稳定的锁模脉冲，在1068 nm的中心波长与397 kHz的基本重复率。
We demonstrate an ultralong cavity, all-fiber, all-normal-dispersion Yb-doped fiber laser that is passively mode locked by a semiconductor saturable absorber mirror (SESAM). Without any discrete dispersion-compensation components or conventional spectral filters, the SESAM works together with the strongly chirped pulse and the nonlinearity induced spectrum broadening to perform a filtering-equivalent function, thus stabilizing the mode locking. The laser generates 4.3 nJ stable mode-locked pulses with a 397 kHz fundamental repetition rate at a 1068 nm central wavelength.
