Abstract

Recently it has been suggested that an atom interacting with a stochastic field suffers a shift of its resonance frequency.^[1] This so-called “stochastic realization shift” depends in part on the correlation between phase and amplitude fluctuations of the field and is predicted to be observable in precision spectroscopy experiments employing semiconductor lasers. In this paper we argue that in a semiconductor laser the nature of the phase-amplitude coupling is such that the shift can only be observed under special conditions.
