Laser – Wikipedia, wolna encyklopedia Laser – urządzenie emitujące promieniowanie elektromagnetyczne z zakresu światła widzialnego, ultrafioletu lub podczerwieni, wykorzystujące zjawisko emisji wymuszonej
Laser | Definition, Acronym, Principle, Applications, Types | Britannica Laser, a device that stimulates atoms or molecules to emit light at particular wavelengths and amplifies that light, typically producing a very narrow beam of radiation The emission generally covers an extremely limited range of visible, infrared, or ultraviolet wavelengths

Laser - Jak działa i gdzie jest wykorzystywany? - Botland Podstawowy laser, taki jak czerwony laser rubinowy, składa się z pręta z kryształów rubinu z lustrem na każdym końcu i lampy błyskowej Rozbłysk światła z lampy błyskowej dodaje energii wewnątrz pręta, pobudzając atomy rubinu i wytwarzając cząstki światła zwane fotonami
Laser definicja i przykłady - Naukowiec. org Laser jest urządzeniem emitującym promieniowanie bazującym na zjawisku emisji wymuszonej Angielska nazwa LASER pochodzi od pierwszych liter wyrażenia " wzmocnienie światła przez wymuszoną emisję promieniowania"
NIFs Guide to How Lasers Work A laser is created when electrons in the atoms in optical materials like glass, crystal, or gas absorb the energy from an electrical current or a light That extra energy “excites” the electrons enough to move from a lower-energy orbit to a higher-energy orbit around the atom’s nucleus
What Is a Laser? How Does It Work? - Optics Mag The word “laser” is an acronym for “light amplification by stimulated emission of radiation ” Lasers have many uses, including cutting and welding materials, measuring distance, and treating medical conditions
What Are Lasers And How Do They Actually Work? - ScienceAlert The most powerful laser designed to date can be found at the European Extreme Light Infrastructure facility in Romania Its lasers are some of the most intense in the world, generating insanely brief pulses of photons, protons, neutrons, and neutrinos with incredible energy
How Lasers Work - HowStuffWorks But what is a laser? What makes a laser beam different from the beam of a flashlight? Specifically, what makes a laser light different from other kinds of light? How are lasers classified? In this article, you'll learn all about the different types of lasers, their different wavelengths and the uses to which we put them (like laser pointers)
