Efficiency factors of absorption Kabs (a), scattering Ksca (b), and extinction Kext (c) of laser radiation with wavelength 532 nm by gold NPs with the following shapes and ambiences: sphere placed in water (1), in blood (2), in protein (3), in ethanol (4), and infinite rod (5–7) in water with angles between direction of laser radiation propagation and main axis of nanorod: 90° (5), 45° (6), and 0° (7). Parameters ∆T0/E0 for spherical gold particles in water for tP = 1 × 10−8 (8), 1 × 10−10 (9), 1 × 10−12 (10) c, λ = 532 nm. Solid lines (1–7) refer to the left axis, and short dashed lines (8–10) refer to the right axis. Sphere radii are in the range r0 ∼ 5–100 nm, for rod r0 means its radius
