Shaped nondiffracting beams.

چکیده
We demonstrate that nondiffracting beams can be generated with an arbitrary transverse shape. In particular, we show that the azimuthal complex modulation of the angular spectra of Helmholtz-Gauss wave fields constitutes a degree of freedom sufficient to tailor nondiffracting beams with an intensity pattern of choice.

NONDIFFRACTING OPTICAL BEAMS: physical properties, experiments and applications
The controversial term ”nondiffracting beam” was introduced into optics by Durnin in 1987. Discussions related to that term revived interest in problems of the light diffraction and resulted in an appearance of the new research direction of the classical optics dealing with the localized transfer of electromagnetic energy. In the paper, the physical concept of the nondiffracting propagation is ...
متن کاملUltrashort highly localized wavepackets.
The recently introduced concept of radially non-oscillating, temporally stable ultrashort-pulsed Bessel-like beams we referred to as needle beams is generalized to a particular class of highly localized wavepackets (HLWs). Spatio-temporally quasi-nondiffracting pulses propagating along extended zones are shaped from Ti:sapphire oscillator radiation with a spatial light modulator and characteriz...
متن کاملApplication of nondiffracting beams to wireless optical communications
In wireless optical communications, information is carried by coherent laser beams propagating through the free space. In realized communication channels, the standard beams created directly in the laser resonator are utilized. In recent time, an increasing attention has been focused on the so-called nondiffracting beams generated by auxiliary optical systems. In this paper, the theoretical and...
متن کاملNondiffracting interference patterns generated with programmable spatial light modulators.
Nondiffracting beams are of interest for optical metrology applications because the size and shape of the beams do not change as the beams propagate. We have created a generating pattern consisting of a linear combination of two nondiffracting patterns. This pattern forms a nondiffracting interference pattern that appears as a circular array of nondiffracting spots. More complicated multiplexed...
متن کاملFeatures of the Gouy Phase of Nondiffract- Ing Beams
It is shown how the linear Gouy phase of an ideal nondiffracting beam of ±(k − kz)z form, with kz being the projection of the wavevector of modulus k of the plane wave spectrum onto the propagation axis z, is built from a rigorous treatment based on the successive approximations to the Helmholtz equation. All of different families of nondiffracting beams with a continuum spectrum, as Bessel bea...
