Free-Electron Laser Explainer Video

An explainer video on how free-electron lasers (FELs) work — roughly 3 minutes 20 seconds, 1920×1080 landscape, with diagrams, ambient music and sound effects. The prompt is only three lines of French: it asks for something educational, with photorealistic imagery and schematics, plus music and sound effects — and names no tool. Well suited to physics explainers, a YouTube education channel, or classroom clips.
