Paper Abstract

A simple method for characterization the quality of anti-relaxation coatings of vacuum optical cells filled with alkalimetal vapors is proposed. This method is based on the registration of the temporal dependence of the intensity of the fluorescence from irradiated alkali atoms by pulsed light at resonance. Here it is shown that in order to find quality of coating it is enough to have the value of fluorescence decay speed and the ratio between the intensities of the fluorescence at the beginning and at the end of the laser pulse. The duration of laser pulses considered is of the order of tens of milliseconds - long enough to reach a steady state.
