| 摘要: |
| 在真空背景下的实验表明，当微秒量级的强脉冲激光与靶材相互作用时，由于靶材的升华，激光维持爆震波依然存在。爆震波产生的压缩波传入靶内，该应力波的作用是材料破坏的重要因素。而强脉冲激光引起的汽化反冲压力、热应力和烧蚀破坏也是不可忽视的因素。实验还表明，在真空背景下维持爆震波足以将后续激光屏蔽。 |

| Abstract: |
| When a high-power pulsed Laser beam interacts with a target in the time of the order of microsecond，the experimental results show that the Laser-supported detonation wave yet occurs due to a sublimation of the target in a vacuum background. A compression wave generated by this Laser-supported detonation wave propagates into the target，this wave is a significant factor for damage of the target，but the recoil pressure of vaporization，the thermal stress and ablation damage of the target to irradiation by the high-power pulsed Laser are also factors that can not be neglected. Experiments also show that the follow-up Laser radiation can be shielded by the Laser-supported detonation wave when the Laser-supported detonation wave occurs in the vacuum background. |
