Microobject manipulations using laser beams with nonzero orbital angular momentum

Three-dimensional light bullets in heterogeneous medium of carbon nanotubes with metallic conductivity

“…An increased focus on similar pulses is due to a wide range of practical applications, such as ultra-high resolution microscopy, data transfer via fiber-optic communication lines, micro-and nanoparticle manipulations, etc. [12][13][14][15]. The importance of practical applications and considerations mentioned above give considerable impetus to the present research.…”

Optical trapping of air-borne light-absorbing particles with various laser beams

“…There are various methods of forming such HOBs that have a predetermined crosssectional shape [20][21][22][23][24]. Changing the cross-sectional shape of the beams can change the shape of the region in which trapped particles will be moved.…”

Diffractive optical elements for capturing and controlled rotation of micro-objects

“…Most of the used vortex beams have a distinct ring structure. But there are light beams that have a more complex structure [5,6], in the form of closed light lines. Optical actuator for micromechanical systems [7 -12] is typically considered as the practical use of such light beams, but there are many other practical issues in the field of micromanipulation using vortex beams [13,14].…”
