Abstract

The spectrum of the luminescence in the far wing of the atomic spectral line due to the atom-surface collisions between cesium atoms and sapphire surface is obtained experimentally. A cw diode laser operating at the wavelength of 852.1 nm resonant to the 6S_1/2 - 6P_3/2 transition in the free Cs atoms was used to excite the luminescence of atomic vapors. To avoid atom-atom collisions a specially designed spectroscopic cell with two sapphire windows only 3 μm apart was employed. The wings were measured for the detuning up to 200 cm^-1 on both sides ofthe atomic spectral line. Besides the wings, luminescence at the wavelength of 894.3 nm corresponding to the 6S_1/2 - 6P_1/2 transition was observed. Notwithstanding high quenching probability, more than 0.5% of the atoms leave the surface in the state of another fine-structure component.
