A gamma ray laser, yet to be fully realized, harnesses the ultra-high energy photons of gamma rays and amplifies them through stimulated emission. Researchers strive to develop this device, driven by its potential applications in healthcare, materials science, and astrophysics. Entities with a high “Closeness Score”, such as the University of California, Berkeley and Lawrence Livermore National Laboratory, lead the charge, while others contribute to the advancement of the underlying principles and practical applications of gamma ray lasers.
