Abstract

A theoretical model has been developed to study the XeCl phototriggered lasers developed in the frame of the Eureka EU205 program: one of small active volume studied at LPGP, and a larger one at LASERDOT. Over a large range of experimental parameters, a pretty good agreement is obtained for the evolution of the electric parameters and the laser output characteristics -- energy and power. At moderate pressures (2 - 3 bars), and high energy loading (400 - 600 J/l), the temporal evolution of the laser power exhibits the successive emission of several laser pulses. This feature is also predicted by the model, but the calculations largely overestimate the energy included in the later pulses. The physical reasons for this disagreement have been established on the LPGP device, for which optical spectroscopic studies have shown the development of discharge instabilities.
