Saturated absorption in SF(6) with double-velocity selection.
Doppler-free saturated absorption of a weak CO(2) laser probe on SF(6), which is caused by two noncollinear pump beams, is reported. A small-linewidth angular dependence was observed and can be predicted in agreement with a fifth-order perturbation calculation for a two-level atom.
