… For mode-locking over a wide wavelength range based on the single SWCNT-SA
developed in the present work, we chose four bulk solid-state lasers operating at
wavelengths between 1 and 2 µm. Yb:KLuW, Cr:forsterite, Cr:YAG and Tm:KLuW were used
as the laser gain materials. The basic … In swnmary, we presented a novel octave
spanning saturable absorber based on single-walled carbon nanotubes. An optimized
fabrication process with two different kinds of SWCNTs enabled the fabrication of a unique …
Abstract
Octave spanning saturable absorber possessing operation bandwidth of~ 1000 nm is fabricated on the basis of single-walled carbon nanotubes and applied for mode-locking of different bulk lasers in the 1 and 2 μm spectral range.
