通过使用高功率激光实验，形成了在环境气体来源的均匀磁化等离子体中传播的超临界无碰撞激波，其均匀性比以前的实验更高。周围的等离子体不会被激光发射后早期产生的等离子体污染。虽然观察到的发展激波不具有固定的下游结构，但它具有磁化超临界激波的一些特征，这些特征得到了考虑激光与目标相互作用的有限时间影响的一维全颗粒细胞模拟的支持。
A developing supercritical collisionless shock propagating in a homogeneously magnetized plasma of ambient gas origin having higher uniformity than the previous experiments is formed by using high-power laser experiment. The ambient plasma is not contaminated by the plasma produced in the early time after the laser shot. While the observed developing shock does not have stationary downstream structure, it possesses some characteristics of a magnetized supercritical shock, which are supported by a one-dimensional full particle-in-cell simulation taking the effect of finite time of laser-target interaction into account.
