Dual-wavelength passively Q-switched erbium-doped fiber laser with MWCNTs slurry as a saturable absorber

In this work, a compact, stable dual-wavelength Q-switched laser has been demonstrated, with a multi-walled carbon nanotubes (MWCNTs) slurry as a saturable absorber (SA) which is independent of any host polymer. The MWCNTs slurry is fabricated and the peak shift is investigated using Raman spectrosc...
