Schawlow, Arthur Leonard (shô`lō), 1921–99, American physicist, b. Mount Vernon, N.Y., grad. Univ. of Toronto (Ph.D. 1949). Although his research focused on optics, in particular, lasers laser [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 phenomenon was discovered in 1911 by Kamerlingh Onnes, who found that the resistance of mercury dropped suddenly to zero at a temperature of about 4.2°K;.
