Photon source

A photon source is a device or system that produces light particles called photons, which are the fundamental units of electromagnetic energy. These sources can generate photons in various ways, such as by heated materials emitting thermal radiation, electric currents causing atoms to glow, or lasers producing highly focused and coherent light. Photon sources are essential in many technologies, including imaging, communication, and scientific research, allowing us to generate specific types of light with desired properties for different applications.
