.Ablation pressure of the shock wave generated by laser interaction with solid targets[J].Optoelectronics Letters,2007,3(5):394-396 Ablation pressure of the shock wave generated by laser interaction with solid targets ZHENG Zhi-yuan ZHANG Yi ZHAO Chang-chun HAO Hui-ying LU Xin LI Yu-tong ZHANGJie [1]School of Materials Science and Technology, China University of Geosciences, Beijing 100083, China [2]Beijing National Laboratory for Condensed Matter Physics, Institute of Physics, Chinese Academy of Sciences, Beijing 100080, China Abstract:       The time evolution process of the plasma generated by laser pulse interaction with solid target in air is observed by optical shadowgraph imaging technique. The ablation pressure of the shock wave generated with the plasma is calculated analytically.It is found that plasma expansion in perpendicular and lateral directions are both proportional to t2/5 with t as delay time, and the ablation pressure reaches 108 Pa.
