First Laser - Google Logo celebrates 16 May 2008
A Laser is an electronic-optical device that emits coherent light radiation. The term “laser” is an acronym for Light Amplification by Stimulated Emission of Radiation.A typical laser emits light in a narrow, low-divergence monochromatic (single-coloured, if the laser is operating in the visible spectrum), beam with a well-defined wavelength. In this respect, laser light is in sharp contrast with such light sources as the incandescent light bulb, which emits light over a wide area and over a wide spectrum of wavelengths. The first working laser was demonstrated on May 16, 1960 by Theodore Maiman at Hughes Research Laboratories.
Now why this definition here ?
Because Google is celebrating 16 May 2008 for the First Laser.
