摘要：

Two-dimensional laser cooling based on velocity-selective coherent population trapping is investigated theoretically for the J = 1 <-> J = 1 atomic transition. Wave vectors and polarizations of three laser beams are chosen to realize a coherent superposition of three degenerate ground states. For the first time forces related to Doppler and interference effects are combined with coherent population trapping to realize a very efficient cooling. Numerical solutions are presented for laser cooling of helium atoms.
