本文研究了基于碳纳米管（CNT）的可饱和吸收体对固体激光器的被动锁模。这些新型吸收体是通过将掺杂有碳纳米管的聚合物旋涂到商用介质激光镜上来制造的。我们获得宽带人工饱和吸收镜超快的恢复时间，而不使用外延生长技术和完善的旋涂工艺允许基于各种各样的衬底材料的设备的制造。本文讨论了Nd：玻璃和Er/Yb：玻璃激光器被动锁模的初步结果。在Er/Yb的情况下：玻璃，我们报告了我们所知的最短脉冲产生的自启动配置的基础上Er/Yb：块玻璃：68 fs（45 fs傅立叶极限）在1570 nm波长的脉冲重复率为85 MHz。(c)2005年，美国光学学会。
We demonstrate passive mode locking of solid-state lasers by saturableabsorbers based on carbon nanotubes (CNT). These novel absorbers are fabricated by spin-coating a polymer doped with CNTs onto commercial dielectric laser-mirrors. We obtain broadband artificial saturable absorber mirrors with ultrafast recovery times without the use of epitaxial growth techniques and the well-established spin-coating process allows the fabrication of devices based on a large variety of substrate materials. First results on passive mode locking of Nd:glass and Er/Yb:glass lasers are discussed. In the case of Er/Yb: glass we report the to our knowledge shortest pulse generated in a self-starting configuration based on Er/Yb: bulk-glass: 68 fs (45fs Fourier-limit) at 1570 nm wavelength at a pulse-repetition rate of 85 MHz.
