The Doppler Effect causes a broadening of the spectral lines obtained from gaseous samples. However, this broadening mechanism can be eliminated by a technique known as saturated absorption spectroscopy. This technique utilizes counter-propogating laser beams to create in Doppler-free spectra that are characterized by sharp resonances. In this experiment, a diode laser ...
