Homogeneous broadening — If an optical emitter (e.g. an atom) shows homogeneous broadening, its linewidth is its natural linewidth (see spectral linewidth). In contrast, an inhomogeneously broadened emitter has a broader linewidth than the natural. Broadening in laser… … Wikipedia
Emission spectrum — The emission spectrum of a chemical element or chemical compound is the spectrum of frequencies of electromagnetic radiation emitted by the element s atoms or the compound s molecules when they are returned to a lower energy state. Each element s … Wikipedia
