A method for microparticles manipulation by tunable powerful ring laser beam is proposed. The method is based on a Fourier transformation of a conical light beam. The method has been realized experimentally with the laser radiation with wavelength of 0.633 . We investigated a space intensity distribution of the field depending on a conicity angle of the tunable conical light beam shaped by a telescope system. An optimal region of the one-ring light field has been determined for influence to media and materials. Ring light fields can be applied to produce photonic structures having a form like ring, circle or crescent.
Key words: annular light field, Fourier transformation, Bessel light beam, microparticle manipulation
