我们表明，在平面内的二维传播和聚焦的激光诱导冲击波的结果在增强的纳米结晶的高度有序的热解石墨。在整个二维冲击聚焦技术，它能够清楚地区分激光诱导和冲击诱导的转换/过渡，我们的研究结果建立的冲击波的作用在转换/过渡过程中。这种配置可以打开一个替代路径的激光冲击制造石墨化合物的方式，并将获得真实的时间调查的冲击波介导的相变。
We demonstrate that in-plane 2D propagation and focusing of a laser-induced shock wave result in enhanced nano-crystallization of highly ordered pyrolytic graphite. Throughout the 2D shock focusing technique, which enables to clearly distinguish between the laser-induced and the shock-induced transformation/transition, our findings establish the role of the shock wave during the transformation/transition process. This configuration could open the way to an alternative path for laser shock fabrication of graphitic compounds and would give access to real time investigation of shock waves mediated phase transitions.
