We present a three-dimensional plasma mirror model based on the relativistic oscillating mirror (ROM) framework, optimized for high-performance numerical simulations of laser-radiation reflection with orbital angular momentum (OAM). By leveraging CPU/GPU parallelization, the model achieves significant acceleration compared to traditional particle-in-cell (PIC) methods while maintaining accuracy in simulating high-order harmonic generation (HOHG). This hybrid CPU–GPU approach ensures both efficiency and scalability, making the model suitable for large-scale simulations. Modern computational techniques not only enhance performance but also enable rapid exploration of complex physical scenarios that were previously computationally prohibitive.

摘要

We present a three-dimensional plasma mirror model based on the relativistic oscillating mirror (ROM) framework, optimized for high-performance numerical simulations of laser-radiation reflection with orbital angular momentum (OAM). By leveraging CPU/GPU parallelization, the model achieves significant acceleration compared to traditional particle-in-cell (PIC) methods while maintaining accuracy in simulating high-order harmonic generation (HOHG). This hybrid CPU–GPU approach ensures both efficiency and scalability, making the model suitable for large-scale simulations. Modern computational techniques not only enhance performance but also enable rapid exploration of complex physical scenarios that were previously computationally prohibitive.
