Ultrafast absorptive and refractive nonlinearities in multi-walled carbon nanotube film
H. I. Elim, W. Ji, G. H. Ma +3
By using femtosecond laser pulses at a wavelength range from 720 to 780 nm, we have observed absorptive and refractive nonlinearities in a film of multi-walled carbon nanotubes gro…
