Plasma surface high-order harmonics generation (SHHG) driven by intense laser pulses on plasma targets enables a high-quality extreme ultraviolet (EUV) source with high pulse energy and outstanding spatiotemporal coherence. Optimizing the performance of SHHG is important for its applications in single-shot imaging and EUV absorption spectroscopy. In this work, we demonstrate the optimization of laser-driven SHHG by an improved Bayesian strategy. A traditional Bayesian algorithm is first employed to optimize the SHHG intensity in a two-dimensional parameter space. Then, an improved Bayesian str...
