抜粋

We report saturable absorber materials in the 1.5 μm band that consist of poly-methyl-methacrylate (PMMA) and polystyrene (PS) polymers with single-wall carbon nanotubes (SWNTs). A very uniform dispersion of SWNT in PMMA and PS polymers has been realized by using chlorobenzene or tetrahydrofuran as a dispersion solvent. These materials, which are as thick as 1 mm, are easily optically polished on both surfaces. This was difficult to achieve with previous thin-film materials. By incorporating PMMA/SWNT as a saturable absorber, a 171 fs pulse is successfully generated in a passively mode-locked fiber laser.
