LSTM Surrogate Model Accelerates Second‑Order Nonlinear Optics Simulations by 252× to Millisecond Scale

A team from Stanford, UCLA and SLAC built a high‑fidelity LSTM surrogate that predicts sum‑frequency‑generation fields with millisecond‑level latency, achieving a 252‑fold speedup over split‑step Fourier simulations while preserving sub‑percent accuracy across thousands of pulse‑shaping configurations.
