摘要：

Analytical characteristics (LTE existence, excitation temperature, plasma plume expansion, duration of analytical spectral lines) of the plasma formed at atmospheric pressure after sharply focused laser beam/solid surface interaction were under investigation. At the time interval of analytical interest (100-400 ns) microplasma was found under LTE conditions with excitation temperature up to 10,000 K and its volume was spatially stabilised.
