The active Brownian motion of single dust particles in a three-dimensional electrostatic DC discharge trap under the action of laser radiation was experimentally studied. The experiment used spherical particles of melamine formaldehyde (MF), part of the surface of which had a copper coating (Janus particle). A comparison of two-dimensional and three-dimensional analysis methods for root-mean-square displacements was carried out. The average kinetic energy of motion of dust particles at different laser irradiation intensities was determined.
