Abstract

This paper presents a method for the construction of micrometer non-diffracting beams in absorbing media. Such beams, named micrometer Frozen Waves, are composed by continuous superposition of Bessel beams and can assume, approximately, any desired longitudinal intensity pattern. It will be obtained solutions representing zero and first order Frozen Waves with diffraction-attenuation-resistance and possessing longitudinal intensity patterns chosen on demand. A wide range of applications can benefit from such structured beams, as optical tweezers, atom guiding, remote sensing, and medical treatments.
