我们测量了两束激光（脉冲宽度为1 ns，1 × 10（15）W cm（-2））聚焦在平面固体靶上产生的等离子体中的磁场重联。同时光学探测和质子网格偏转揭示了两个高速，准直外流射流和0.7-1.3 MG的磁场在焦斑边缘。汤姆逊散射测量的重连层是一致的，在这个区域的高电子温度。
We present measurements of a magnetic reconnection in a plasma created by two laser beams (1 ns pulse duration, 1x10(15) W cm(-2)) focused in close proximity on a planar solid target. Simultaneous optical probing and proton grid deflectometry reveal two high velocity, collimated outflowing jets and 0.7-1.3 MG magnetic fields at the focal spot edges. Thomson scattering measurements from the reconnection layer are consistent with high electron temperatures in this region.
