Web1 One Rayleigh range is defined as the point on either side of the waist where the beam diameter increases to the square-root of 2 times the waist diameter (i.e., 1.414 d). Two Rayleigh ranges would be the point at which the beam is 2.828 times the waist diameter. WebApr 7, 2024 · The Rayleigh-Plateau instability occurs when surface tension makes a fluid column become unstable to small perturbations. At nanometer scales, thermal fluctuations are comparable to surface energy densities. Consequently, at these scales, thermal fluctuations play a significant role in the dynamics of the instability. These microscopic … WebJun 21, 2024 · When Equation (\ref{9.31}) is introduced into the expression for the electric field, Equation (\ref{9.27}), the imaginary part of 1 ... for a typical gas laser operating in the visible.
