Lasers produce a highly concentrated beam of radiation. This effect is based on the principle of induced release of photons. The fundamental parts website of a laser system contain an active medium, a pump source, and optical resonators. The active medium is excited by the pump source, causing particles to transition to higher energy levels. Upon returning to their ground state, these atoms emit photons that are amplified within the resonators, resulting in a coherent and monochromatic beam of light.
