Bistability and passive Q-switching of a CO2 laser with saturable absorber
Abstract
The coexistence of bistability and repetitive passive Q-switching of a CO2 laser with a gaseous saturable absorber has been investigated experimentally. With CH3F as the saturable absorber, bistability has been observed simultaneously with passive Q-switching, whereas with CH3OH only one of these phenomena can exist, as demonstrated for the first time. The measured features of both systems can be explained qualitatively by rate-equation theory.
