Extinction cross section σ ext is decreased from 2 to 20 times depending on r 0, for example, for r 0 = 40 nm is decreased from σ ext = 6.2 × 10-10 cm2 (r 1/r 0 = 1) to σ ext = 3 × 10-11 cm2 (r 1/r 0 = 2) for λ = 633 nm. Figure 6 Efficiency cross sections σ sca (a) and σ ext (b) of laser radiation.
Cross section of absorption σ abs for pure vapor bubble is much smaller than σ abs for system NP-shell and does not present at Figures 1 and 2. Figure 1 Efficiency cross sections of absorption σ abs, scattering σ sca, and extinction σ ext of laser radiation.
The expressions for the optical characteristics of two-layered sphere (efficiency cross sections of absorption, scattering, and extinction) are presented in terms of the amplitude coefficients given by the theory of diffraction of electromagnetic radiation on two-layered spherical particle [33, 32, 34, 35].
On the basis of this, we made the formulae for the envelope and its offset curve and worked to calculate the area efficiency of cross section and curvature of hypotrochoid.
In addition, an extremely significant biophysical size, defining the muscle, is the coefficient of unit efficiency of cross section, k.
The applicability of this approach is limited because large differences in Stokes shifts are not common among FP pairs, and mKeima and EGFP have relatively low two-photon absorption efficiency, or cross sections, at the optimal wavelength of excitation (900 nm) [ 1, 3, 4].
