To investigate the saturable absorption properties of different wavelengths Figure 6b illustrates the nonlinear optical NLO transmittance as a function of input laser peak intensities at wavelengths o

In order to examine the saturable absorption characteristics of various wavelengths, Figure 6(b) demonstrates the nonlinear optical (NLO) transmittance as a function of input laser peak intensities at 355 nm, 532 nm, and 1064 nm wavelengths.
