摘要: We have performed a photon-echo experiment on the 555.6-nm intercombination line of atomic Yb vapor which demonstrates that an intense laser field acts to inhibit dephasing resulting from velocity-changing collisions. This finding implies optical Bloch equations, assume relaxation is independent strength driving field, cannot correctly describe behavior gas-phase samples in all regimes.
