In the 1960s, Glauber established the field of quantum optics and advanced Einstein's observation that light can be considered both as waves and as a stream of particles. His work helped to explain the fundamental differences between diffuse sources of light such as light bulbs, which are characterized by a mixture of frequencies that are not in phase, and the intense light of laserslaser
[acronym for light amplification by stimulated emission of radiation], device for the creation, amplification, and transmission of a narrow, intense beam of coherent light. The laser is sometimes referred to as an optical maser.
