Along with the conventional optogalvanic (OG) signal an anomalous ligh-induced response has been detected in hollow cathode discharge. This response manifests itself both in the amplitude and time-resolved OG reactions. The anomalous OG signal is found to be less dependent on the absorbing optical transition and yet, more informative on the parameters of the plasma medium, that is the OG detector. This circumstance is proposed for usage in four applications based on the behaviour of the anomalous OG signal. The latter is taken as a spectral marker, as an amplified quasi-amplitude signal as well as a sensitive tool in monitoring procedure.
