论文摘要
诱导的康普顿散射（ICS）是强烈的电磁辐射与稀有血浆之间的非线性相互作用。 尽管脉冲星的磁层是在自然界中发生ICS的潜在引用，但到目前为止尚未发现ICS特征。 不检出ICS特征的原因之一是，由于其非线性性质和缺乏实验性确认，我们仍然无法获得对这种非线性血浆相互作用的具体理解。 在这里，我们提出了一种可能在实验室实验了解IC的方法，尤其是使用最新的短脉冲激光器。 我们发现，IC的散射光在频谱中具有特征性特征。 这些签名将在当前的一些激光设施中观察到。 特征频谱是可以预测的，我们可以诊断出特征中的散射等离子体的性质。
Induced Compton scattering (ICS) is a nonlinear interaction between intense electromagnetic radiation and a rarefied plasma. Although the magnetosphere of pulsars is a potential cite at which ICS occurs in nature, the ICS signatures have not been discovered so far. One of the reasons for non-detection of the ICS signatures is that we still do not attain the concrete understanding of such nonlinear plasma interactions because of their nonlinear nature and of the lack of experimental confirmations. Here, we propose a possible approach to understand ICS experimentally in laboratories, especially, with the use of the up-to-date short-pulse lasers. We find that the scattered light of ICS has characteristic signatures in the spectrum. The signatures will be observed in some current laser facilities. The characteristic spectrum is quantitatively predictable and we can diagnose the properties of the scattering plasma from the signatures.
