Paper Abstract

A new sensor based on optical beam shading technique for the investigation of mechanical effects during laser-metal interaction is developed. This sensor is applied to detect the laser-induced plasma explosive impact and deformation process during the explosion when a Q-switched laser is focused on a metal. The experimental results indicate that elastic deformation and plastic deformation associated with the event induced by laser plasma the same time. This technique has the advantages of high-frequency response, simple structure, and nondestructive examination.
