For Rayleigh particles in a medium of index nb, the scattering force (Fscat) in the direction of the incident power is Io/12856(m^2-1)^2 * no * c^34 * m^+2, where I (=100 mW) is the intensity and m (= nb/nw) is the effective index. The gradient force of radiation pressure (Fgrad) in the direction of the intensity gradient for a spherical Rayleigh particle of polarizability ability a is qu * n * g * r^3 * (m^2-1) * vE^2 * 2 * 2 * m^2-2. For a Gaussian beam of focal spot size wo, the ratio of R = Fgrad/Fscat in the Rayleigh regime (1 >> D) is Fgrad = 3/3 * n * λ * 5 * R = Fscat * 64 * m^-1 * m^+2. Calculate R to determine whether the particle is trapped (i.e., R > 1) or untrapped. It is known that the particle diameter 2r = 80 nm, A = 514.5 nm, the effective index of polystyrene latex spheres in water m = n/nw = 1.65/1.33 = 1.24, and 2wo = 1.5 = 0.58 m. 514.5 nm LIGHT H2O CELL
