Paper Abstract

We have observed Ar2* emission at 126 nm by use of a high intensity laser pulse as an excitation source. Kinetic analysis revealed that high-intensity laser-produced electrons via optical field induced ionization (OFI) process initiated the Ar2* production kinetics. Ar2* production kinetics initiated by OFI electrons was mainly governed by the three-body association process, which was analogous to the case of electron beam excitation. The use of a hollow fiber controlled propagation characteristics of a high intensity laser pulse in a high-pressure gas, leading to the increase of the excimer emission intensity
