We study the properties of laser plasma at normal atmospheric pressure, which is induced on the surface of silicon and indium under the action of an Nd: YAG laser beam with a wavelength of 1064 nm and a pulse duration of 10 ns using the method of laser spectroscopy. The electron density in the plasma was determined by the Stark expansion method for spectral lines of laser plasma. The electron temperature was calculated using the Boltzmann equation.
