论文摘要
我们详细研究了在Euler-Heisenberg有效理论框架内的脉搏形拉瓜仪束中的刺激的光子发射。我们详细介绍了光子发射振幅的分析结构，并通过分析每个签名的相位缩放来识别其主导和亚基部分。我们确定了三个不同的非线性签名：轨道角动量（OAM）翻转（$ \ ell：1 \ rightarrow -1 $），更高的谐波生成（$ \ ell：1 \ rightArrow 2 $）和谐波减少（$ \ ell：$ \ ell：1 \ rightarrow 0 $）。我们在各种脉冲碰撞场景下估计每个签名的信号光子产量，我们详细解释。我们还概述了可能探究这些签名的前瞻性实验设置。
We investigate in detail the stimulated photon emission in pulse-shaped Laguerre-Gauss beams of arbitrary mode decomposition within the framework of Euler-Heisenberg effective theory. We elaborate on the analytic structure of the photon emission amplitude and identify its dominant and sub-dominant parts by analyzing each signature's phase scaling. We identify three distinct nonlinear signatures: the orbital angular momentum (OAM) flip ($\ell:1 \rightarrow -1$) , higher harmonic generation ($\ell:1 \rightarrow 2$) and harmonic reduction ($\ell:1 \rightarrow 0$). We estimate signal photon yield for each signature under various pulse collision scenarios we explain in detail. We also outline a prospective experimental setup that may probe these signatures.
