Time-averaged spectra of a laser plume and the time dynamics of the most intense spectral lines are studied under neodymium laser irradiation (1.06 μm; (1/3) x 10~8 W/cm~2; 20 ns; 12 Hz) in vacuum (3-5 Pa) at distances of 1 and 7 mm from a silver target. The obtained results are used to construct a time-averaged energy distribution of excited states of silver atoms and to estimate the relaxation time and electron temperature.
