Experimental study demonstrates shifted and broadened correlation-time peaks in a helium-neon laser, confirming steady-state threshold dynamics under multiplicative noise.
Two-time intensity correlations in a laser with multiplicative white noise have been studied experimentally. Multiplicative noise was introduced by applying a Gaussian-noise voltage to an intracavity acousto-optic modulator in a He:Ne laser operating near threshold. We observe both a shift and a broadening of the peak in the correlation-time versus mean-light-intensity curve. These observations are in agreement with the previous measurements of the steady-state properties of the laser near threshold in the presence of multiplicative noise.
