提供包含在几个立方波长（λ（3））的焦点体积中的能量的激光可以使用最小的能量产生具有最大梯度的相对论强度。通过粒子模拟，我们发现，通过脉冲本身产生的相对论等离子体镜的偏转和压缩，在λ（3）激光脉冲反射中可以有效地产生单个200阿秒脉冲。从一个带电层的相干辐射的分析模型证实了脉冲压缩，并在良好的协议与模拟。这种新的技术是有效的（接近10%），可以产生从毫焦耳到焦耳量级的单阿秒脉冲。
Lasers that provide an energy encompassed in a focal volume of a few cubic wavelengths (lambda(3)) can create relativistic intensity with maximal gradients, using minimal energy. With particle-in-cell simulations we found, that single 200 attosecond pulses could be produced efficiently in a lambda(3) laser pulse reflection, via deflection and compression from the relativistic plasma mirror created by the pulse itself. An analytical model of coherent radiation from a charged layer confirms the pulse compression and is in good agreement with simulations. The novel technique is efficient (similar to10%) and can produce single attosecond pulses from the millijoule to the joule level.
