Sub-Doppler Spectroscopy by Using Sodium Nanocell

2008

International audience; We present for the first time the results of the sub-Doppler spectroscopy realized with a nanocell filled with a Sodium metal. The thickness L of the gap between the windows (which determines the length of the atomic vapor column) has a wedge in the vertical direction varying from 100 to 900 nm. It is demonstrated that the use of a nanocell with the thickness L=lambda/2 and L=lambda, where lambda is the wavelength of the dye laser radiation resonant with D2 line of Sodium, allows one to provide sub-Doppler spectroscopy of the Transmission and Fluorescence spectra of D2 lines of Sodium (lambda ~ 590 nm). A cw dye laser radiation with the linewidth of ~1 MHz and tunabl…

Sub-Doppler features of optical processes in the Rb extremely thin cell filled with an additional buffer gas.

2009

International audience; Comparison of the resonant absorption and fluorescence in the extremely thin cell (ETC) filled with pure Rb with another one filled with Rb and Neon gas with the pressures 6 Torr and 20 Torr is provided. The effect of the collapse and revival of Dicke-type narrowing is still observable for the thickness L=λ/2, and L=λ, where λ is a resonant laser wavelength 794 nm (D1 line of the Rb), i.e. the spectra of the resonant absorption and fluorescence demonstrate the sub-Doppler narrowing for the thickness L=λ/2 and broadening for the thickness L=λ. It is important to note, that in an ordinary Rb cell with the thickness L in the range of 1mm- 10 cm filled with buffer gas, w…
