WebCoherence is one of the unique properties of laser radiation. It arises from the stimulated light emission process, providing the amplification of emitted photons, which have a definite relation to each other, i.e., they are in phase. The coherent properties of light are described by temporal and spatial coherence. WebOct 24, 1997 · Abstract. Coherent extreme-ultraviolet radiation extending to wavelengths below the carbon K edge at 4.37 nanometers (nm) has been generated at a repetition …

Why is a laser beam monochromatic and coherent?

WebLaser light is emitted as a relatively narrow beam in a specific direction. Ordinary light, such as coming from the sun, a light bulb, or a candle, is emitted in many directions away from the source.
