As the correlation time of the frequency fluctuations increases from zero to infinity, the laser line shape changes from Lorentzian to Gaussian in a continuous way. It is shown that for intermediate and strong fields, the average intensity of fluorescence in the case of a resonant broadband ...
The line shape function is normalized to unity and can be regarded as a probability distribution. An important point is that if two broadening mechanisms are independent, the line shape resulting from the operation of both mechanisms is simply the convolution of the two line shapes resulting from...
The aim of the theory is the calculation of the injected-laser line shape. This is done for the first time for a single-mode He-Ne laser working at 3.39 μm. The results are experimentally confirmed. 展开 关键词: autoionizing states electron-atom collisions angular distributions ...

The absorption line shapes of the R1(1)-R1(5) lines of HF have been measured as a function of pressure for pure HF and with Ar and Kr as buffer gases by means of a cw tunable FB (II)-type color-center laser operating in the wavelength range from 2.25 to 2.65 μm. Line-broadening...
Various processes affect the Raman line shape, shifting it away from a symmetrical Lorentzian, Gaussian, or Voigt function. Fano resonances cause the loss of symmetrical line shape, leading to a nonsymmetrical signature shape. Fano resonance is the result of a purely quantum process, with the ...

A light-diffusing fiber31, whose internal nanostructures scatter out a small fraction of light from its core, was wrapped into a helical shape with a depth range stretching over 80 mm (Fig. 2a). After coupling a picosecond pulsed laser into the fiber, the internal laser pulse evolution ...
