在高强度、大能量、皮秒激光脉冲产生的实验室等离子体中，观测到了相对论电子磁化状态下的磁场重联。用激光驱动的几千特斯拉磁场实现的磁重联条件与黑洞系统吸积盘日冕中的磁重联条件相当，即，天鹅座X-1我们观察到的粒子能量分布的重联外流射流，其中具有幂律分量在高能量范围内。观测到的光谱的硬度可以解释吸积黑洞系统的硬态x射线发射。
Magnetic reconnection in a relativistic electron magnetization regime was observed in a laboratory plasma produced by a high-intensity, large energy, picoseconds laser pulse. Magnetic reconnection conditions realized with a laser-driven several kilotesla magnetic field is comparable to that in the accretion disk corona of black hole systems, i.e., Cygnus X-1. We observed particle energy distributions of reconnection outflow jets, which possess a power-law component in a high-energy range. The hardness of the observed spectra could explain the hard-state x-ray emission from accreting black hole systems.
