Induced Compton scattering (ICS) is a nonlinear interaction between intense electromagnetic radiation and a rarefied plasma. Although the magnetosphere of pulsars is a potential site at which ICS occurs in nature, ICS signatures have not been discovered so far. One of the reasons for the non-detection of ICS signatures is that we still do not possess a concrete understanding of such nonlinear plasma interactions because of their nonlinear nature and the lack of experimental confirmations. Here, we propose a possible approach to understand ICS experimentally in laboratories, specifically, with the use of the up-to-date short-pulse lasers. We find that the scattered light of ICS has characteristic signatures in its 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.

对大功率激光设备诱发康普顿散射的实验观察

感应康普顿散射（ICS）是强电磁辐射和稀薄等离子体之间的非线性相互作用。尽管脉冲星的磁层是自然界中发生ICS的潜在场所，但迄今为止尚未发现ICS签名。未检测到ICS签名的原因之一是，由于此类非线性等离子体相互作用的非线性性质和缺乏实验确认，我们仍不具备具体的了解。在这里，我们提出了一种可行的方法来通过实验室实验来了解ICS，特别是使用最新的短脉冲激光器。我们发现ICS的散射光在其光谱中具有特征性标志。在一些当前的激光设备中将观察到签名。
