Several types of instabilities in passive Q switching and optical bistability are observed in a number of 10-/mu/m laser lines in a N/sub 2/O laser with intracavity saturable absorbers such as NH/sub 3/, SF/sub 6/, C/sub 2/H/sub 4/, C/sub 2/H/sub 3/Cl, and CCl/sub 2/F/sub 2/. The observed pulse shapes are reproduced well by a calculation based on the recently proposed rate-equation model. Characteristic dependences of passive Q switching and bistability on the laser parameters are explained with a phase diagram derived theoretically.
