Abstract

Statistical distributions of phase and intensity of light in the free-running emission of a ruby laser working well above the oscillation threshold are studied using a incoherent holographic technique. It is shown that a coherent speckle pattern is emitted in each spike, and also, in certain conditions, in the integrated emission. It is inferred that free-running ruby lasers can be used to extend recently-developed speckle interferometric techniques to the microsecond time domain.
