论文摘要
我们证明，在高功率激光脉冲与结构化固体血浆通道的相互作用中，随机辐射发射的清晰量子特征表现出明确的量子特征，揭示了研究光子发射的量化性质的新途径。与较早的发现相反，我们观察到，与包括经典辐射反应在内的计算相比，在量子辐射模型中，通过研究薄等离子体通道目标实现的总辐射能量非常短，在量子辐射模型中显着更大。通过详细的分析分析和精制的测试粒子模型，通过完整的动力学等离子体模拟证实，我们证明了这种反直觉行为是由于通过驱动激光器向设置的能量持续供应所致。我们对拟议的设置的实验意识评论，这是在即将到来的高强度激光设施中可行的，因为可以制造所需的薄目标以及现有技术提供的驱动激光脉冲。
We demonstrate that in the interaction of a high-power laser pulse with a structured solid-density plasma-channel, clear quantum signatures of stochastic radiation emission manifest, disclosing a novel avenue to studying the quantized nature of photon emission. In contrast to earlier findings we observe that the total radiated energy for very short interaction times, achieved by studying thin plasma channel targets, is significantly larger in a quantum radiation model as compared to a calculation including classical radiation reaction, i.e., we observe quantum anti-quenching. By means of a detailed analytical analysis and a refined test particle model, corroborated by a full kinetic plasma simulation, we demonstrate that this counter-intuitive behavior is due to the constant supply of energy to the setup through the driving laser. We comment on an experimental realization of the proposed setup, feasible at upcoming high-intensity laser facilities, since the required thin targets can be manufactured and the driving laser pulses provided with existing technology.
