As mentioned above, it is clear from its historical derivation that the original Schawlow–Townes equation is a four-fold approximation of the fundamental laser linewidth. Starting from the fundamental laser linewidth Δ ν L {\displaystyle \Delta \nu _{\rm {L}}} derived above, by applying the four approximations … See more Laser linewidth is the spectral linewidth of a laser beam. Two of the most distinctive characteristics of laser emission are spatial coherence and spectral coherence. While spatial coherence is related … See more One of the first methods used to measure the coherence of a laser was interferometry. A typical method to measure the laser linewidth is self-heterodyne … See more Laser linewidth from high-power, high-gain pulsed-lasers, in the absence of intracavity line narrowing optics, can be quite broad and in the case of … See more History: First derivation of the laser linewidth The first human-made coherent light source was a maser. The acronym MASER stands for "Microwave Amplification by Stimulated Emission of Radiation". More precisely, it was the See more The laser linewidth in a typical single-transverse-mode He–Ne laser (at a wavelength of 632.8 nm), in the absence of intracavity line narrowing optics, can be on the order of 1 … See more • Laser • Fabry–Perot interferometer • Beam divergence • Multiple-prism dispersion theory See more WebMar 1, 2007 · The theory of the fundamental laser linewidth as expressed by the Schawlow-Townes formula is extended to include the amplification of vacuum field fluctuations as … WebLaser linewidth theory was pioneered by Schawlow and Townes1 and further developed in Refs. 2 and 3.
