Increasing ellipticity usually suppresses the recollision probability drastically. In contrast, we report on a recollision channel with large return energy and a substantial probability, regardless of the ellipticity. The laser envelope plays a dominant role in the energy gained by the electron, and in the conditions under which the electron comes back to the core. We show that this recollision channel efficiently triggers various nonlinear and nonperturbative phenomena—such as multiple ionization—with an elliptically polarized pulse.

椭圆极化脉冲触发的包络驱动碰撞。

椭圆度的增加通常会大大抑制重新碰撞的可能性。相比之下,无论椭圆度如何,我们都会报告具有较大返回能量和较大概率的再碰撞通道。激光包络在电子获得的能量以及电子返回核心的条件下起主要作用。我们表明,这种碰撞通道有效地触发了带有椭圆偏振脉冲的各种非线性和非扰动现象,例如多次电离。
