WebAug 18, 2015 · The typical FWHM linewidth of a an LED is given by $$\Delta{}\lambda= \frac{\lambda^2}{hc}3kT$$ The $3kT$ comes from the uncertainty of the initial and final energy levels of the carrier transitions generating the light, due to their thermal excitation. This works out to about 27 nm in the red region, for example. WebThe FWHM for hydrogen lines is ( 43) where Ne is the electron density. The half-width parameter α 1/2 for the H β line at 4861 , widely used for plasma diagnostics, is tabulated in the table below for some typical temperatures and electron densities [ 33 ].

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 ammonia maser operating at 12.5 mm wavelength that was demonstrated by Gordon, Zeiger, and Townes in 1954. One year later the same authors derived theoretically the linewidth of their device by making the reasonable approximations that their ammonia maser
