强激光与固体靶相互作用时，通过辐射反应效应有效地产生高能光子。这些光子接收大部分入射激光能量，并且光子通过目标的能量传输对于理解激光-物质相互作用至关重要。为了理解能量输运，我们新开发了一个Particle-in-Cell程序，通过引入光子宏观粒子，包含了光子与物质的相互作用。进行测试模拟，并与模拟使用粒子输运代码，这表明了良好的协议。
When intense laser beams interact with solid targets, high-energy photons are effectively generated via radiation reaction effect. These photons receive a large portion of the incident laser energy, and the energy transport by photons through the target is crucial for the understanding of the laser–matter interactions. In order to understand the energy transport, we newly developed a Particle-in-Cell code which includes the photon–matter interactions by introducing photon macro-particles. Test simulations are performed and compared with simulations using a particle transport code, which shows a good agreement.
