Figure 3: Z-scan curves for ILs composed by Tf2N and (a) BMI+ measured with  mW, (b) HMI+ with  mW, (c) OMI+ with  mW, and (d) DMI+ with  mW. The minimum beam waist was μm and the aperture transmittance for all measurements. White dots correspond to the experimental data and the red curves are the fittings using (6).
