gamma-ray lasers

Gamma-ray lasers, or gamma-ray amplification by stimulated emission of radiation, are theoretical devices that would emit highly focused beams of gamma rays—high-energy electromagnetic radiation. Unlike conventional lasers that use visible light, gamma-ray lasers would operate at much higher energies, potentially enabling advanced applications in medicine, materials science, and astrophysics. However, they face significant technical challenges, such as creating and maintaining a stable medium for emission. While the concept is exciting and could revolutionize various fields, practical gamma-ray lasers have not yet been developed.
