Microscale solute flow probed with rotating microbead trapped in optical vortex
Weronika Lamperska, Jan Masajada, Sławomir Drobczyński
The dynamics of solute flow in the microscopic chamber can be studied with optical tweezers. A method based on the metallic microbeads trapped in the focused optical vortex beam is…
Off-axis vortex beam propagation through classical optical system in terms of Kummer confluent hypergeometric function
Ireneusz Augustyniak, Weronika Lamperska, Jan Masajada +2
The analytical solution for the propagation of the laser beam with optical vortex through the system of lenses is presented. The optical vortex is introduced into the laser beam (d…
Optical vortex torque measured with optically trapped microbarbells
Weronika Lamperska, Jan Masajada, Sławomir Drobczyński +1
Optical vortex beams carry orbital angular momentum and thus exert torque on illuminated objects. A dielectric microtool - a microbarbell - is used in a two-laser optical tweezers…
Polygonal micro-whirlpools induced in ferrofluids
Marcin Bacia, Weronika Lamperska, Jan Masajada +2
We report on the observation of the polygonal whirlpools in the thin layer of ferrofluid under illumination with a laser beam carrying optical vortex and in the presence of a verti…
