摘要：
The spectral characteristics of plasma generated on the surface of human hairs under various focusing conditions (lenses with focal lengths 50, 100, and 150 mm) by short (9 ns) laser pulses with energies from 50 to 50 mJ were experimentally studied by elemental analysis along the length of the samples. The minimal energies of the laser pulses were obtained. The optimal conditions for recording emission lines of magnesium and calcium in the studied samples were determined.
