Generation of off-axis optical traps based on beams with a power-law phase dependence on the radius

The paper considers laser beams with a power-law phase dependence on the radius, which make it possible to form optical traps for capturing particles and molecules using a set of scattering and collecting axicons, which are complemented by a focusing lens, as well as a phase element with a deflecting wavefront in the case of off-axis trap formation. The possibility of forming off-axis optical traps of different sizes with the possibility of changing their position and using their combinations is shown.
