XeF ground-state dynamics in a laser discharge

Abstract
The time evolution of gain and absorption in an XeF laser discharge is studied using a pulsed uv dye‐laser probe and timing system with ±7‐nsec resolution. The dissociation rate of the lowest vibrational level of the XeF ground state as a function of helium buffer pressure is found to have a slope of 1×104 sec−1 Torr−1 (±15%).
