Laser Beam
A laser beam is a concentrated beam of light that is produced by the stimulated emission of photons from a laser. The laser beam is characterized by its high intensity, coherence, and directionality. The high intensity of the laser beam allows it to be used for cutting, welding, and drilling in various industrial applications. The coherence of the laser beam allows it to be used for holography, interferometry, and other precision measurement applications. The directionality of the laser beam allows it to be used for communication, ranging, and remote sensing applications in space and astronautical engineering. The laser beam can be produced in various wavelengths, including visible, ultraviolet, and infrared, depending on the type of laser used.
