The interaction of laser radiation with aqueous dispersion of only bovine serum albumin (BSA) 25 wt. [%], only bovine collagen (BC) 2 wt. [%], and 25 wt. [%] BSA with single-walled carbon nanotubes (SWCNTs) 0.3 wt. [%] and 2 wt. [%] BC with 0.3 wt.[%] SWCNT was studied. The beam was absorbed mainly by nanotubes, that confirmed by the small value of the nonlinear absorption coefficients for aqueous dispersed media with BSA 6 cm GW-1, as well as dispersion with BK 4 cm GW-1 and the large values of coefficients for these media with addition of SWCNTs, respectively 350 cm GW-1 and 70 cm GW-1. Determination of nonlinear optical parameters was obtained by the method of fixed sample location. Knowledge of the values of these parameters allowed calculating theoretical curve of Z-scan with open aperture what made possible to compare with the experimental data. © 2018, Peter the Great St. Petersburg Polytechnic University.
