LASERS The Laser/Atom Connection A laser is a device that controls the way that energized atoms release photons. Laser is an acronym for Light intricacy by Stimulated Emission of Radiation, which describes very succinctly how a laser works! Although there are many types of lasers, only occupy certain essential features. In a laser, the lasing learn is pumped to get the atoms into an excited severalize. Typically, very intense flashes of chromium steel or electrical discharges pump the lasing medium and create a large collection of excited- resign atoms (atoms with higher energy electrons).
It i s necessary to ask a large collection of atoms in the excited state for the laser to work efficiently. In general, the atoms are excited to a level that is two or three levels above the background state. This increases the degree of population inversion. The population inversion is the number of atoms in the excited state versus the ground state. Once the lasing medium is pumped, it contains a ...If you want to get a full essay, order it on our website: OrderCustomPaper.com
