    "body_text": "Inertial-confinement fusion depends on a laser pulse whose changing intensity drives a carefully staged implosion. Designing that pulse normally requires expensive simulation and manual iteration. The proposed Laser Pulse Shape Design System reverses the direction: desired outcomes and target-pellet configurations become inputs, and a generative model proposes a pulse under a multi-objective loss encoding physical and experimental constraints. The authors also add constraint conditioning, inpainting and gradient-based editing so researchers can adjust selected portions of a pulse rather than regenerate it wholesale, and they study transfer on a limited set of real shots. This is a design framework and early transfer study, not evidence of net-energy fusion or an autonomous experimental facility; its claims remain bounded to the reported simulations and limited experimental data.",
