Optical bistability, limiting, and other pulse shaping effects are observed in compact Fabry-Perot resonators containing SF6. The gas, in cells as short as 1 mm, is excited with smooth 100-ns transversely excited atmospheric CO2 laser pulses. The optical nonlinearity responsible for these effects is well described by a four-state kinetic model with unsaturable excited state absorption.
