The output of a laser-diode-pumped Nd:YAG laser with an intravcavity-doubling crystal exhibits large-amplitude fluctuations and longitudinal-mode instabilities. results experimental theoretical investigation these instabilities are described. arise from coupling the longitudinal modes oscillator by sum-frequency generation in nonlinear crystal. A rate-equation theory multilongitudinal-mode intracavity-doubling is presented that includes terms modeling frequency-doubling processes.
