Experimental study of kerr effect and nonlinear absorption of Multi Walled Carbon Nanotubes

摘要

In this research, the influence of pulse width and energy on the nonlinear refractive index (712) and nonlinear absorption (β) in Multiwalled carbon- nanotubes (MWCNTs) were experimentally studied. For this purpose, three different MWCNTs concentrations were used and were dispersed in a Polyvinyl alcohol (PVA) solution. We found a highly dependence of n_2 and β with the MWCNTs concentration, optical intensity, and pulse width.
