Abstract

Temporal correlations of radiation intensities of a multimode Fabry-Perot semiconductor laser are investigated. Strong intensity correlations with a fixed phase shift between different longitudinal modes of the laser are revealed. The second g^(2) and third g^(3) order intensity correlation functions are studied to clear the character of the intermodal coupling.
