研究了激光驱动相对论电子束的汤姆逊散射产生阿秒X射线的可能性。对于在等离子体丝中激光有质动力加速产生的≤200As，预测了在3-300keV范围内以∼160As脉冲形式产生的超过106光子/S的数十MeV电子束，峰值亮度为≥5×1020光子/(S mm2mra20.1%带宽)。我们的研究表明，这项工作中讨论的物理方案可以用于超快(阿秒)x射线源，这对时间分辨原子物理最有利，被称为“阿秒物理”。
The possibility of producing attosecond x-rays through Thomson scattering of laser light off laser-driven relativistic electron beams is investigated. For a ≤200-as, tens-MeV electron bunch produced with laser ponderomotive-force acceleration in a plasma wire, exceeding 106 photons/s in the form of ∼160 as pulses in the range of 3–300 keV are predicted, with a peak brightness of ≥5 × 1020 photons/(s mm2 mrad2 0.1% bandwidth). Our study suggests that the physical scheme discussed in this work can be used for an ultrafast (attosecond) x-ray source, which is the most beneficial for time-resolved atomic physics, dubbed “attosecond physics.”
