A single-mode N2O laser with NH3 as a saturable absorber is found to exhibit chaotic passive Q switching with multipeaked pulses. The chaotic dynamics is strongly correlated with vibrational relaxation mechanism in the laser medium. The phenomenon is predicted, and its characteristic behavior is well explained, by the rate-equation analysis recently developed for the case of instability in CO2 lasers.
