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