ABSTRACT
We measure the composition of collective mode resonances in the intensity fluctuations of a multimode laser by separating the laser modes with Fabry-Perot interferometers and applying transfer function and cross-spectrum techniques. Comparison of the transfer function with the power spectrum of the fluctuations in individual cavity modes shows features that are attributable to the difference between single frequency excitation and noisy excitation of the collective mode resonances. These data together with the cross-spectra of the modal intensity fluctuations, highlight a need for greater understanding of the mechanisms of noisy excitation of a nonlinear oscillator array. © 2000 American Institute of Physics.
