Abstract

As an integral part of the steady development of copper vapour lasers over the past 30 years, computer modelling has been used to provide an insight into complex issues relating to the plasma kinetics and evolution of the optical laser fields. For example, calculations of the behaviour of the electron temperature and the flux rates of various processes are of critical importance when interpreting kinetic data obtained from experiments. However, these parameters are virtually impossible to measure experimentally due to the rapid temporal variation of the plasma variables. Numerical modelling has been employed to unravel the complicated and highly-coupled multi-species kinetics which evolves both spatially and temporally through the excitation (lasing) phase and interpulse relaxation period. Over the history of CVL development, there has been a steady increase in sophistication and reliability of the numerical models. This has been due primarily to the improved accuracy of the electron-impact impact cross-sections for copper, the availability of spatially and temporally resolved species population measurements for comparison with model predictions [1–4], and a steady increase in computing power. In this paper, the current status of computing modelling of CVL’s is presented. This includes a summary of the currently available cross-sections, and a discussion of the published models for the kinetics and the optical laser fields.
