The pecularities of the Near-surface Optical Plasma Generation during Laser Welding

摘要：

The processes in near-surface laser induced plasma in specific conditions of laser welding were investigated. The model of the process of the thermalonization associated with the interaction of laser radiation and metal target was studied to acquire temperature dynamics and the plasma absorptance.Threshold values of temperature for the appearance of he thermal instability and near-surface optical plasma generation have been obtained.
