Název v původním jazyce

Optical trapping in secondary maxima of focused laser beam

Popis výsledku v původním jazyce

Single beam optical tweezers hold particles behind the focal plane due to the high gradients of optical intensity present in a focused laser beam. However, description of this optical field based on a vectorial theory of diffraction reveals that the highintensity focal area is accompanied by several secondary maxima on the optical axis as well as by a structure of rings away of the optical axis. Such a structure can be found in beams exhibiting spherical aberrations as well as in beams where aberrationis corrected. Here, we discuss possibility to use these secondary maxima of aberration-corrected beams as the optical traps. We present the properties of such traps created by objective lenses of various numerical apertures that are focusing plane waves.
