We study experimentally the interaction of the shortest at present (23-fs) , relativistically intense (20-TW), tightly focused laser pulses with underdense plasma. MeV electrons constitute a two-temperature distribution due to different plasma wave-breaking processes at a plasma density of 10(20) cm(-3). These two groups of electrons are shown numerically to constitute bunches with very distinctive time durations.
我们通过实验研究了目前最短（23飞秒）、相对论强度（20太瓦）、紧聚焦激光脉冲与低密度等离子体的相互作用。在等离子体密度为10（20）厘米（-3）时，由于不同的等离子体破波过程，兆电子伏电子构成了双温度分布。数值结果表明，这两组电子形成了具有非常独特持续时间的束团。
