Collision process of two shockwaves
两个冲击波相互碰撞的演化过程

The collision of the two shockwaves induced by laser confined ablation is investigated by time-resolved shadowgraph. Through the observation of the temporal and spacial evolution of the two shockwaves, it is found that the shockwaves do not interact with each other but interact with the plasma induce by ablation in the collision.
