Also known as light amplification by stimulated emission of radiation, lasers
وسیلهای برای تولید پرتوهای نوری همدوس، تقریباً موازی و تقریباً تکفام، در ناحیههای فروسرخ و مرئی و فرابنفش
A laser is a device that produces an intense, focused beam of light by stimulating atoms or molecules to emit radiation in a coherent way. Lasers matter because they have practical applications across many fields—in this case, they're being used as guide stars to help telescopes see more clearly through the atmosphere.
