我们证明了使用碳纳米管可饱和吸收体的镱光纤激光器锁模可以产生20 ps到2 ns的脉冲，重复频率分别在21 MHz和177 kHz之间，取决于腔长。非线性极化演化不是锁模的原因。即使在纳秒范围内，也可以观察到干净的单脉冲，并且脉冲序列表现出低抖动。结合极大的啁啾，这些特性适用于啁啾脉冲放大系统。(C) 2009年美国物理研究所。(doi: 10.1063/1.3207828)
We demonstrate that mode-locking of ytterbium fiber lasers with a carbon nanotube saturable absorber can produce pulses ranging from 20 ps to 2 ns at repetition rates between 21 MHz and 177 kHz, respectively, depending on cavity length. Nonlinear polarization evolution is not responsible for mode-locking. Even in the nanosecond regime, clean single pulses are observed and the pulse train exhibits low jitter. Combined with extremely large chirp, these properties are suited for chirped-pulse amplification systems. (C) 2009 American Institute of Physics. [doi:10.1063/1.3207828]
