This paper presents the principles and application of a super-resolution (SR) technique,
based on a L1-Norm minimization procedure. In particular, the technique is applied to improve
low-resolution resolution spectra as obtained from the optogalvanic effect in Neon and Argon
discharges over the 413-423 nm wavelength range. By applying the super-resolution algorithm
to the experimental data, a surprising 70-fold reduction of the linewidth is achieved allowing to
resolve prior indistinguishable peaks. It is found that further improvements on the resolution
are limited by the signal to noise ratio of the original spectra. The importance of a suitable
mathematical representation of the experiment and the discussion on other applications of this
super-resolution technique in spectroscopy are also presented.
