Level-crossing spectroscopy of atoms dressed by optical photons in degenerate four-wave mixing.
We investigate degenerate four-wave mixing on the 607.4-nm line of neon using crossed-polarized beams. We show that the line shape changes dramatically in the presence of a magnetic field. Narrow resonances are observed, which are interpreted as level-crossing resonances in the energy diagram of the dressed atom.
