    The Quantum Physics Behind Laser Technology

    Meilleure citation de The Quantum Physics Behind Laser Technology

    “

    Laser light is fundamentally different because it relies on stimulated emission, where a photon encounters an excited atom and stimulates it to emit an identical clone—same frequency, same phase, and same direction.
