The development of spectrally very narrow, tunable-wavelength lasers has paved the way for numerous modern experiments on light-matter interactions: saturated absorption, two-photon absorption, electromagnetically induced transparency, atom manipulation and cooling…

The goal of this project is to explore this field by conducting a nonlinear spectroscopy experiment on rubidium. An extended-cavity laser diode is used to explore the energy structure of the first electronic levels of this atom (5S, 5P, and 5D levels) and then compare it to theoretical predictions.
