We aim to study the turbulence in a typical massive star-forming region G35.20-0.74 N with a sufficient spatial resolution to resolve the thermal Jeans length, and a spectral resolution to resolve the thermal linewidth. Methods.

NettetHomogeneous Broadening Definition: the increase in the linewidth of an atomic transition caused by effects which affect different radiating or absorbing atoms in the same way German: homogene Verbreiterung Category: physical foundations How to cite the article; suggest additional literature Author: Dr. Rüdiger Paschotta NettetThe obtained linewidth of the transition spectra is about 10 MHz, which is are some greater than the natural linewidth and limited by the broadening from the probe and lattice light. Our experiment that measures the frequencies of the 3 P 0,2-3 S 1 transitions of 171 Yb atoms in an optical lattice differs from all previous work [33], [34]. trudel banoffee

NettetIn such systems, a major factor affecting performance will be the amount of light fed back into the laser. The emphasis in most previous work 1–3 has been on linewidth narrowing arising from external optical feedback. However, If the phase of the feedback is not controlled, the laser line may broaden or split under the influence of feedback. Nettet6. mar. 2024 · Homogeneous Broadening.

NettetLine broadening and shift. There are a number of effects which control spectral line shape. A spectral line extends over a range of frequencies, not a single frequency (i.e., it has a nonzero linewidth). In addition, its center may be shifted from its nominal central wavelength. There are several reasons for this broadening and shift. Nettet8. feb. 2024 · We estimate a fundamental radiative linewidth of 1.54±0.17 meV, owing purely to finite radiative lifetime in the absence of nonradiative dephasing processes. …

NettetIn atomic physics, Doppler broadening is broadening of spectral lines due to the Doppler effect caused by a distribution of velocities of atoms or molecules.Different velocities of the emitting (or absorbing) particles result in different Doppler shifts, the cumulative effect of which is the emission (absorption) line broadening. This resulting line profile is known … NettetThe linewidth of the EPR spectra is relates with the spin‐chain system [6].
