Abstract
A quantum cascade distributed feedback laser operating at 5.2 μm is used to obtain sub-Doppler resolution limited saturation features in a Lamb-dip experiment on the R(13.5)1/2 and R(13.5)3/2 transitions of NO. The dips appear as transmission spikes with full widths of ∼ 4.3 MHz. At this resolution the 73 MHz Λ-doubling of the R(13.5)3/2 line, which is normally obscured by the 130 MHz Doppler broadening, is easily resolved.
