Nontrivial intensity correlation from a coherent continuous-wave laser beam
Binod Joshi, Thomas A. Smith, Yanhua H. Shih
Quantum correlations with a normalized value of ${g}^{(2)}(\ensuremath{\tau})>1$ are typically observed in light in a thermal state (e.g., light from a star or incandescent bulb). Here, the authors demonstrate that similar correlations are present in a continuous-wave laser beam consisting of a large number of longitudinal modes modeled as coherent states.
