Lézerrendszerek

Lézerrendszerek (Light Amplification by Stimulated Emission of Radiation systems) refer to devices that produce and direct a highly concentrated beam of light. The core component of any laser system is the gain medium, which can be a solid, liquid, gas, or semiconductor. When energy is supplied to the gain medium (pumping), its atoms or molecules become excited and then return to their lower energy state by emitting photons. A resonant cavity, typically formed by mirrors, reflects these photons back and forth through the gain medium. This process amplifies the light through stimulated emission, where photons trigger the emission of identical photons, leading to a coherent and monochromatic light beam. One mirror is partially transparent, allowing a portion of the amplified light to exit as the laser beam. Laser systems are characterized by their wavelength, power output, beam divergence, and pulse duration, depending on the specific application. They find widespread use in fields such as telecommunications, medicine (surgery, diagnostics), manufacturing (cutting, welding), scientific research, and consumer electronics.
