Definition of Doppler broadening in English:

Doppler broadening

noun

mass nounPhysics

The broadening of spectral lines as a result of the different velocities of the emitting atoms giving rise to different Doppler shifts.
〔物理〕多普勒谱线增宽
Example sentencesExamples
- Doppler broadening is due to the distribution of atomic velocities (speed and direction), which each have a Doppler shift with respect to an observer.
- For atomic spectra in the visible and UV, the limit on resolution is often set by Doppler broadening.
- Alternatively, they are not optimum for elimination of Doppler broadening.
- In a low pressure gas, the main source of broadening is Doppler broadening from the thermal motion of the atoms or molecules of the gas.
- When the driving field is resonant, at a suitable Doppler width, we can get a maximum value of the gain without inversion, which is much larger than that obtained when Doppler broadening is absent.
