Radiation forces study of a Laguerre Gaussian beam type TEM*₀₁ on a dielectric sphere in the Rayleigh scattering regime. Dyna rev.fac.nac.minas [online]. 2019, vol.86, n.210, pp.187-193.

From the invention of the Optical Tweezer (OT) in 1986, these devices have been considered as high-level tools for research in the areas such as biology and microbiology. A theoretical study obtaining equations for gradient and scattering forces that exert an OT when the illumination beam is a doughnut-shaped mode TEM*01 linearly polarized is realized. This work focuses on the behavior of radiation forces on a dielectric sphere in the Rayleigh regime. In order to facilitate the phenomenological analysis of the behavior of the radiation forces a graphical user interface is created.

Keywords : optical tweezer; beam doughnut-shaped; Rayleigh’s regime..
