A Free-Electron Laser (FEL) is a type of laser that generates high-intensity, coherent electromagnetic radiation — typically in the form of laser light — using free electrons instead of bound electrons in atoms, which is the case in traditional lasers. The key features of FELs include: 1. **Free Electrons**: Instead of using electrons bound to atoms (as in conventional lasers), FELs use beams of free electrons.
