One of the most important properties of laser light is its spectral purity and coherence. This unique quality has been important for the study of many new physical phenomena using laser sources that operate from the vacuum ultraviolet to the far infrared. An understanding of the mechanisms responsible for the broadening of the linewidth is necessary for the development of laser sources with sufficient spectral purity for various applications.
