Phys. Rev. A 62, 013810 (2000) [11 pages]Anomalies, symmetries, and asymmetries in the relaxation oscillation spectra of multimode standing-wave solid-state lasersReceived 21 October 1998; revised 22 October 1999; published 14 June 2000 When the laser medium only partially fills the cavity of a multimode solid-state laser, there are significant changes in the spectral profile of the emission, the intensity fluctuation power spectra, and modulation transfer functions in comparison with lasers which have media that entirely fill the cavity. These effects are computed according to several approximate models for the multimode interactions and compared with experimental measurements. Symmetries and asymmetries in the multimode optical spectrum have corresponding features in the relaxation oscillation spectra. Changes in the laser cavity detuning and laser excitation lead to relatively abrupt changes in some variables (modal intensities, low-frequency relaxation oscillations) while the total intensity and largest relaxation oscillation frequency vary as they would for a single-mode laser. © 2000 The American Physical Society URL:
