In NIF as in most large lasers intense flashes of white light from giant flashlamps pump electrons in large slabs of laser glass to a higher-energy state that lasts only about one-millionth of a second. Second the light released from a laser is coherent which means that it is ordered and controlled. Laser Technology Definition Applications And Challenges Physics Metropolia Confluence Some light waves are reflected between two mirrors and cause more atoms to emit light resulting in a narrow intense light beam. . Laser stands for light amplification by stimulated emission of radiation. The acronym LASER stands for Light amplification by stimulated emission of radiation. Laser of different power and application can be produced by using different materials. Attempts to describe the origin of the emission and absorption lines ie the. Researchers have demonstrated the worlds first metasurface laser that produces super-chiral lig
