Abstract
We experimentally studied the spectral characteristics of plasma generated on the surface of human hair under various focusing conditions (by the lenses with a focal length of 50, 100, 150 mm) by short (9 ns) laser pulses with an energy from 5 to 50 mJ in the regime of elemental composition analysis along the length of the samples. The minimal energetic levels of laser pulses were obtained. The optimal conditions for the registration of the emission lines of magnesium and calcium in the studied samples were determined.
