The results obtained in a cell with a distance between windows on the order of several hundreds of nanometers (the so-called “nanocell”) are presented. The nanocell thickness L in the vertical direction changes from 100 to 900 nm. It is shown that the use of a nanocell with thickness L = λ/2, where λ is a laser wavelength resonant to the atomic transition D2 in sodium atoms, provides sub-Doppler resolution of transmission and fluorescence spectra.

Abstract
The results obtained in a cell with a distance between windows on the order of several hundreds of nanometers (the so-called “nanocell”) are presented. The nanocell thickness L in the vertical direction changes from 100 to 900 nm. It is shown that the use of a nanocell with thickness L = λ/2, where λ is a laser wavelength resonant to the atomic transition D2 in sodium atoms, provides sub-Doppler resolution of transmission and fluorescence spectra.File in questo prodotto:
