我们展示了在低密度等离子体中传播的强短激光脉冲激发弓波的新效应。由于激光脉冲能量在横向上扩散，弓波引起电子密度的大规模横向调制。这可以显着增加尾波的电势，因为尾波是在比激光脉冲腰宽得多的区域中产生的。
We show a new effect of the bow-wave excitation by an intense short laser pulse propagating in underdense plasma. Because of spreading of the laser pulse energy in transverse direction, the bow wave causes a large-scale transverse modulation of the electron density. This can significantly increase the electric potential of the wake wave since the wake wave is generated in the region much wider than the laser pulse waist.
