| Abstract: | Major intensity effects were observed in the collision-free CO2 laser-induced dissociation of CF2HCl utilizing real-time laser-excited fluorescence diagnostics. At constant fluence: increasing average pulse intensities by 6 increased dissociation yields 400 fold; pulse mode-locking caused 5–10 fold increases in yield. Induction times reflect threshold behavior. Collisions reduce laser intensity effects. |
