Abstract

In the present paper, we discuss some basic physical problems, related to the particle on the surface, i.e. optical resonance and near-field effects in laser cleaning. Another problem is the dynamics of the particle in adhesion potential. It is shown that the particle performs oscillations, which can be in principal resonantly enhanced. The analysis of thermal deformation shows that 1D thermal expansion of the surface can not explain the experimental results and the 3D effects are of great importance. Some new effects arise due to the thermal contact of the particle with the surface.
