Reversible vacuum Rabi oscillations vs. exponential decay: role of ‘shape’ (or color) of spectral density. WebbThis next demonstration is about the laser line width or the spectral width of the laser radiation. Now theory predicts that the line width of a laser should be very, very narrow, much narrower then a fraction of a Hertz, in fact, of the order of 10 to the minus 3, 10 to the minus 4 Hertz or even smaller. In practice, we don't see that. can aprn practice independently in texas

"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 " - Theory of the fundamental laser linewidth
