We will present our recent theoretical and experimental results related to the behaviour of micro-and nanoparticle placed into nonlinear optical potentials under overdamped or underdamped regime. The two-dimensional optical ratchet rectifies motion of Brownian particles in any direction in the plane, unstable cubic optical potential results in noise-induced particle motion and action of non-conservative optical spin-force leads to orbiting of a levitated particle.
