Abstract:

An additional lowering of the threshold intensities of nonstationary optical breakdown on aerosols by several times compared to the theoretical ones can occur in air due to the gap between the electron and gas temperatures. The gap origin is determined by the "bottle neck" effect in the energy exchange between the internal degrees, of freedom, i.е., by excitation and deexcitation of lower metastable states of О and N atoms in the completely dissociated high temperature air plasma.
