Sub-Doppler Raman saturation spectroscopy.


Sub-Doppler linewidth spectra of the Q(01) (2) transition in deuterium (D(2)) have been obtained by using a stimulated Raman technique analogous to sub-Doppler IR saturation spectroscopy. Two experimental configurations are described that employ alternatively either three or four laser beams at two frequencies. The saturation dip is detected by using an… (More)
