Compensation of Doppler Broadening by Velocity-Dependent Light-Shifts (With 7 Figures)

Velocity-dependent light shifts may be used to suppress the Doppler broadening of an atomic spectral line observed along a given direction. We present emission spectra of $^{20}\mathrm{Ne}$ demonstrating the existence of such an effect for an appreciable portion of the atoms. Various possible applications taking advantage of the high anisotropy of this effect are suggested.Velocity-dependent light shifts may be used to suppress the Doppler broadening of an atomic spectral line observed along a given direction.
