Dynamics of charged particles in optical traps

Analysis and numerical modeling show the possibility of the confinement of semi-relativistic electron motion in large (dimensions⪢wavelength) cylindrical optical traps for low-density (np/ncrit∼0.01) plasmoids. The traps are based on circular polarized cylindrical waves T E mn ( r , ϕ ) . Perspectives of other forms and volume variation of traps are briefly discussed.
