Lasers produce a highly intense beam of light. This occurrence is based on the principle of controlled emission of photons. The fundamental elements of a laser system include an active medium, a pump source, and optical resonators. The active medium is activated by the pump source, causing atoms to transition to higher energy levels. Upon returning to their ground state, these atoms produce photons that are amplified within the resonators, resulting in a coherent and monochromatic beam of light.
