摘要:

激光离子加速的辐射压力加速机制需要高强度的激光脉冲才能有效地起作用。此外,箔在相互作用期间对于入射辐射应该是不透明的,以确保从脉冲到箔的最大动量传递,这需要靶与激光脉冲的适当匹配。然而,在超相对论的制度,这会导致大的加速距离,超过高斯激光脉冲的高激光强度必须保持。结果表明,适当的剪裁的激光脉冲轮廓可以显着减少加速距离,导致紧凑的激光离子加速器,需要更少的能量来操作。

英文摘要:

The radiation pressure acceleration regime of laser ion acceleration requires high intensity laser pulses to function efficiently. Moreover the foil should be opaque for incident radiation during the interaction to ensure maximum momentum transfer from the pulse to the foil, which requires proper matching of the target to the laser pulse. However, in the ultrarelativistic regime, this leads to large acceleration distances, over which the high laser intensity for a Gaussian laser pulse must be maintained. It is shown that proper tailoring of the laser pulse profile can significantly reduce the acceleration distance, leading to a compact laser ion accelerator, requiring less energy to operate.
