We consider the interaction of a high-intensity short laser pulse with an argon gas during optical field ionisation. Modelling in a three-dimensional cylindrical symmetric geometry is performed at various moderately relativistic intensities and positions of the focal plane of the laser beam in the case of both optical gas ionisation and a pre-ionised plasma. The influence of the processes occurring during optical field ionisation of the gas on the generation of wake waves is investigated, and the conditions are found under which intense wake fields are produced in a plasma formed from an inhomogeneous argon gas jet. The possibility of using a gas with a large number of electrons on the outer shell (argon) to excite intense wake waves and accelerate electrons is demonstrated. Despite significant ionisation refraction of the laser pulse on a radially inhomogeneous density profile of plasma electrons formed during optical field ionisation, the region of the parameters of the laser pul...

非均匀等离子体中飞秒激光脉冲对光场电离的唤醒场产生的影响

我们考虑在光场电离期间高强度短激光脉冲与氩气的相互作用。在光学气体电离和预电离等离子体的情况下,在各种中等相对论强度和激光束焦平面的位置上执行三维圆柱对称几何模型的建模。研究了气体光场电离过程中发生的过程对尾波产生的影响,并发现了在由不均匀氩气射流形成的等离子体中产生强尾波场的条件。证明了使用在外壳(氩气)上具有大量电子的气体来激发强烈的尾波并加速电子的可能性。
