Abstract

We introduce a novel and useful concept in stochastic excitation spectroscopy: a pair of complementary noises. This concept realizes a constant power-spectral density over the frequency region of interest by combining two power spectral densities that are complementary to each other. Consequently the pair is free from the limitations associated with a pseudo-random binary code and white noise; the pair is generated in a flexible manner and needs no ensemble averaging to reduce the power-spectral fluctuations. Our theory was supported by the experimental results with the magnetic resonances of Rb atoms.
