Laser Light Is Not Monochromatic at Sharon Sutherland blog

Laser Light Is Not Monochromatic. An ideal monochromatic wave would have to persist for all. These are coherence, directionality, monochromatic, high intensity The photons produced are equivalent to waves of light whose crests and troughs line up (in other words, they are in phase)—and that's what makes laser. Despite the fact that real lasers do not produce exactly one wavelength of light, we still call laser light monochromatic. Real lasers are not perfectly monochromatic because several broadening mechanisms widen the frequency (and energy) of the emitted photons. Laser light has four unique characteristics that differentiate it from ordinary light: Laser light has a much narrower spectrum of wavelengths than a lightbulb, but even laser light can’t be purely monochromatic. A laser is device that emits coherent and monochromatic light. Stimulated emission in lasers makes electrons produce a cascade of identical photons—identical in energy, frequency, wavelength—and that's why laser light is monochromatic. When a gas in the laser absorbs radiation, electrons are elevated to different energy levels. Monochromatic laser light the light from a laser typically comes from one atomic transition with a single precise wavelength.
