摘要
We discuss some physical effects that take place in multifrequency light fields with a nonzero average cube of the electric field, < E3 > not-equal ). We calculated the polar asymmetry in electron emission that is due to interference between two-photon ionization by the fundamental radiation (omega) and one-photon ionization by the second-harmonic (2-omega) wave. The expression for the quasi-static force, which acts on electrons and is proportional to the average cube of the light field, is derived.
