At SLAC\u2019s upgraded Linac Coherent Light Source (LCLS-II), infrared laser pulses are first to green light and then to ultraviolet (UV). The UV pulse strikes a cathode to liberate an electron bunch that is subsequently accelerated and modulated to produce intense X-ray pulses. The temporal shape of the UV pulse directly influences the properties of that electron bunch\u2014and ultimately the quality of the X-rays available for science.<\/p>\n<p>A surrogate model for the nonlinear \u03c7\u00b2 frequency conversion step at the heart of this process is <a href=\"https:\/\/www.spiedigitallibrary.org\/journals\/advanced-photonics\/volume-8\/issue-03\/036004\/Deep-learning-assisted-modeling-for-%cf%872-nonlinear-optics\/10.1117\/1.AP.8.3.036004.full\" target=\"_blank\">reported<\/a> in Advanced Photonics.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Simulating the nonlinear optical physics that underlies ultrafast laser systems is computationally demanding\u2014a practical bottleneck in settings that require rapid feedback.
