Laser Beam A laser beam is a concentrated and coherent stream of photons emitted from a laser device through the process of stimulated emission. Laser beams are characterized by their high intensity, monochromaticity, directionality, and low divergence, making them suitable for various applications in science, technology, medicine, industry, and entertainment. Laser beams can be generated using different types of laser sources, including gas lasers, solid-state lasers, semiconductor lasers, and fiber lasers, each offering unique properties and advantages for specific applications.
Laser beams are widely used for tasks such as cutting, welding, engraving, marking, micromachining, laser surgery, barcode scanning, communication, and scientific research. The characteristics of a laser beam, including its power, wavelength, pulse duration, coherence length, beam profile, and polarization, determine its suitability and effectiveness for different tasks and applications. Laser beams are manipulated, focused, and directed using optical components and beam delivery systems to achieve desired outcomes with precision and efficiency. |
