Doppler broadening

noun

Physics
The broadening of spectral lines as a result of the different velocities of the emitting atoms giving rise to different Doppler shifts.
Example sentences
  • For atomic spectra in the visible and UV, the limit on resolution is often set by Doppler broadening.
  • 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.
  • 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.
