چکیده
Thus P' represents the maximum value of the spectral absorption coefficient if only Doppler broadening occurred; b, bc, and bD denote, respectively, the natural half-width,t the half-width resulting from collision (Lorentz) broadening, and the half-width produced by Doppler broadening; S is the integrated intensity of the spectral line under study whose center lies at wo; m is the mass of the radiating molecule; k equals the Boltzmann constant; T represents the absolute temperature. The total radiant intensity A emitted by a spectral line is

Photonic superdiffusive motion in resonance line radiation trapping Partial frequency redistribution effects.
The relation between the jump length probability distribution function and the spectral line profile in resonance atomic radiation trapping is considered for partial frequency redistribution (PFR) between absorbed and reemitted radiation. The single line opacity distribution function [M. N. Berberan-Santos et al., J. Chem. Phys. 125, 174308 (2006)] is generalized for PFR and used to discuss sev...
متن کاملReplacement of the Lorentz law for the shape of the spectral lines in the infrared region.
We propose a new phenomenological law for the shape of the spectral lines in the infrared, which accounts for the exponential decay of the extinction coefficient in the high-frequency region, observed in many spectra. We apply this law to the measured infrared spectra of LiF, NaCl, and MgF2, finding good agreement over a wide range of frequencies.

متن کاملPolarization-dependent spectral broadening of femtosecond pulses in silicon waveguides
We investigate the polarization dependence of the spectral broadening of femtosecond pulses inside silicon waveguides by using finite-difference time-domain (FDTD) simulations. Our FDTDmodel includes the anisotropic dependency of predominant nonlinear effects in silicon: Kerr effect, two-photon absorption, and Raman effect. In addition, free-carrier absorption and free-carrier dispersion effect...
متن کاملFirst Spectroscopic Measurements on the COMPASS Tokamak
Spectroscopic measurements were performed on the re-installed COMPASS tokamak during the first experiments. The impurity survey spectrometer HR 2000+ was used for registration of the most intense spectral lines in the 457–663nm visible range integrated over the discharge duration. The temporal evolution of integral visible light, Hα and hard X-rays intensities are measured by a photomultipliers...
