Paper Abstract

Mathematical modeling of water droplet explosion in air in the field of CO2-laser radiation (LR) was carried out. Some processes leading to air optical breakdown (OB) initiation in shock wave (SW) were investigated. OB of shock-heated air has been shown to develop in two stages. At the first stage, initial electrons are caused by plasma chemical reactions in heated and compressed air. At the second stage, these electrons, under influence of laser radiation, give rise to an electron avalanche, which leads to air OB.
