Experimental investigation of plasma jet and solid target interaction based on laser-ablation launching approach

Laser-ablation plasma has been regarded as a novel approach for providing high velocity loading in experiment. Axial jet velocity of km/s even higher than 5 km/s could be achieved by employing laser-driven plasma method. On the other side , a wide range of jet temperature and plasma density could also be obtained during the loading process. This paper presents an experimental method to investigate the super high-velocity impact of solid target with gas. A high energy laser-ablation plasma device was established in this work, and plasma with jet velocity above 10 km/s was generated during the experiment. The aerodynamic characteristics of the high-velocity object’s interaction with gas were studied in the experiment. The results of prove that, this work, the method has great potential for applications in the research of many fields including astrophysics, asteroid morphology, and the interaction of aerolith with atmosphere.
