首次利用纯化的单壁碳纳米管作为可饱和吸收体实现了一种新型的工作在1300 nm的被动锁模光纤激光器。可饱和吸收体采用直径受控的CNT，峰值吸收/spl sim/1300 nm，保证在相同波长区域的锁模。环形激光器使用掺镨光纤作为增益介质。脉冲重复频率为3.18 MHz，光谱半宽为0.15 nm。双波长锁模也被证明与1.1 nm的信道间隔。
For the first time, we demonstrate a novel passively mode-locked fiber laser operating at 1300 nm using purified single-walled carbon nanotubes (CNTs) as a saturable absorber. The saturable absorber incorporates diameter-controlled CNTs with peak absorption /spl sim/1300 nm, guaranteeing mode-locking over the same wavelength region. The ring laser uses praseodymium-doped fiber as a gain medium. The pulse repetition rate is 3.18 MHz, and the spectral half-width is 0.15 nm. Dual-wavelength mode-locking is also demonstrated with a channel spacing of 1.1 nm.
