论文摘要
高功率激光器设备可实验访问基本强场量子电动力学过程。要探索的关键效果是非线性的BREIT轮毂过程:通过与强电磁场的相互作用,高能量光子将高能量光子的转化为电子峰值。在实验上观察非线性BREIT轮胎对生产的主要挑战是首先具有合适的高能量光子来源。在本文中,我们概述了一个简单的全光设置,该设置通过使用高功率激光器照射实心目标,通过所谓的$γ$ -Flash机构有效地生成光子。我们考虑这些光子与次级激光器的碰撞,并系统地讨论了在当前和下一代高功率激光器设施下探索非线性BREIT轮毂过程的前景。
High-power laser facilities give experimental access to fundamental strong-field quantum electrodynamics processes. A key effect to be explored is the nonlinear Breit-Wheeler process: the conversion of high-energy photons into electron-positron pairs through the interaction with a strong electromagnetic field. A major challenge to observing nonlinear Breit-Wheeler pair production experimentally is first having a suitable source of high-energy photons. In this paper we outline a simple all-optical setup which efficiently generates photons through the so-called $γ$-flash mechanism by irradiating a solid target with a high-power laser. We consider the collision of these photons with a secondary laser, and systematically discuss the prospects for exploring the nonlinear Breit-Wheeler process at current and next-generation high-power laser facilities.
