Efficiency cross sections σ abs (a), σ sca (b), and σ ext (c) of laser radiation. With wavelength 780 nm by two-layered spherical system gold NP core and water vapor shell with refractive index of vapor m 1 = 1.001-i 0 placed in water for the range of NP radii r 0 = 5 to 100 nm and radii of system r 1 = r 0 (1, pure gold NP, straight line), r 1 = r 0 + 0.1r 0 (2, dotted line), r 1 = r 0 + 1r 0 (3, dashed line), r 1 = r 0 + 2r 0 (4, dashed-dotted line), r 1 = r 0 + 3r 0 (5, straight line), and r 1 = r 0 + 4r 0 (6, straight line), and for homogeneous vapor bubble with r 0 (7, dashed-double dotted line).
