摘要：

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.
