Macro-particle ejection by laser ablation of high-temperature superconductors

A model of cluster-type laser ablation of materials which as a result of the thermochemical reaction can be decomposed into solid and gaseous products, is developed on the basis of the solution of thermoconductivity and mechanical problems. The ablation threshold, size and velocity of macro-particles escaping from YBaCuO superconductor under the pulsed laser radiation, are calculated.
