Study of atomic transition self-broadening and shift with the help of a nano-cell

We demonstrate experimentally that it is possible to detect and measure the self-broadening rate and frequency shift of the rubidium second principal series atomic transitions at very high atomic vapour densities up to ∼ 1017 cm− 3. The experimental procedure includes the usual absorption measurement technique and a sealed-off nano-cell containing Rb vapour operating at high temperatures with a thickness of L = λ /2, where λ is the resonant wavelength (420 nm).
