This is the published version of Cheng Xie, G. Klimeck, and D. S. Elliott. (1 June 1990). "Generation and intensity-correlation measurements of the real Gaussian field". First published in the Physical Review A and is available online at:


The generation of a broadband laser field with well-defined and controllable statistical properties, known as the real Gaussian laser field, has been achieved through the random modulation of the amplitude of a stabilized laser beam. The verification of the field-generation technique is provided by measurements ofthe laser power spectrum (Lorentzian) and by measurements ofthe intensity au- tocorrelation function. The latter is shown to decrease exponentially from an initial value of nearly 3 to a final value of 1 with a decay time related to the inverse bandwidth of the field. The techniques for generating this field and for its characterization are discussed in this paper.
