Simultaneous micromanipulation in multiple planes using a self-reconstructing light beam

Abstract: We present tailoring of three dimensional light fields which act as light moulds for elaborate particle micro structures of variable shapes. Stereo microscopy is used for visualization of the 3D particle assemblies. The powerful method is demonstrated for the class of propagation invariant beams, where we introduce the use of Mathieu beams as light moulds with non-rotationally-symmetric structure. They offer multifarious field distributions and facilitate the creation of versatile particle structures. This gen… Show more

“…The major advantage of self-healing beams is that they can be used through turbulent media [152] and that they are ideal candidates for particle manipulation at different planes [156,157] and in microscopy [158]. The CR phenomenon has been also reported as an efficient tool to generate Bessel beams [62,159,160].…”

“…Non-diffractive pump fields have been utilized in nonlinear optical processes like parametric down conversion [2,3,4,5,6,7], second [8,9,10,11], third [12], and higher-order harmonic generation [13]. Furthermore, the accuracy of optical tweezers [14,15,16], optical trapping [17,18,19,20,21] and the resolution of medical imaging [22,23] have been enhanced by the implementation of diffraction-free beams.…”

“…Despite the ideal nature of BBs (they carry infinite power), they not only have revealed to be a paradigm for understanding wave phenomena, but also have found applications as diverse as in frequency conversion, or in atom trapping and alignment [7]. Of particular interest for us is the finding [8] that the BB is describable in terms of the interference of two conical Hankel beams [5], carrying equal amounts of energy towards and outwards the beam axis, and yielding no net transversal energy flux in the BB.…”
