Abstract
A commercially available neon indicator lamp in a Relaxation Oscillator (RO) configuration has been demonstrated to be capable of detecting light intensities of the order of nanowatts under ambient light conditions with a subpicometer spectral resolution. The RO has also been shown as capable of acting as a wireless light switch with light intensities of the order of 1 µW. Temporal excitation studies have also shown the predominant mechanism describing the observed frequency changes in the RO to be a result of laser perturbation of the neon lamp when it is in the Townsend-discharge region and not in the abnormal glow.
