Free Electron Laser
A Free Electron Laser (FEL) is a powerful tool that generates laser light using high-speed electrons rather than a fixed material to produce the light. In an FEL, electrons are accelerated and then passed through a magnetic structure called an undulator. As the electrons move through the undulator, they emit light that is amplified to produce coherent, highly focused beams across a range of wavelengths, including visible and X-ray light. FELs are valuable in research and industry for studying materials, medical imaging, and many other applications due to their flexibility and intensity.

A free electron laser (FEL) is a powerful type of laser that uses beams of free electrons, rather than atoms, to generate light. In an FEL, electrons are accelerated and passed through a series of magnets that make them oscillate. This movement produces intense light in a specific wavelength range. FELs can be tuned to emit various types of radiation, from infrared to X-rays, making them useful in scientific research, medical imaging, and material studies. Their unique properties allow for high brightness and precise control over the light produced.
