The relaxation oscillator as a resonance photon detector
A commercially available neon indicator lamp in a relaxation oscillator (RO) configuration has been demonstrated 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 capable of acting as a wireless light switch, with light intensities of the order of 1 micro-W. 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.
