Several types of instability in passive Q switching and optical bistability are observed in a number of 10-μm laser lines in a N2O laser with intracavity saturable absorbers such as NH3, SF6, C2H4, C2H3Cl, and CCl2F2. 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.
