title: Experimental measurement of the beam parameters of an electromagnetic Gaussian Schell-model source.
abstract: We report the experimental measurement of the beam parameters of an electromagnetic Gaussian Schell-model (EGSM) source based on the technique for measuring the fourth-order correlation function (i.e., intensity correlation function). Furthermore, we carry out experimental measurement of the intensity distribution of a focused EGSM beam, and we carry out theoretical simulation using the measured beam parameters. Our experimental results agree reasonably well with the theoretical predictions.
