Efficient design procedures for high power C02-laser modules rely on a thorough understanding of the gas discharge as laser source. In this, numerical simulations of the laser plasma can be of substantial help but leave out key features like discharge geometry and gas flow effects. Therefore, efforts should also be put into the measurement of the plasma parameters for a given module. Since Langmuir probes can provide both spatially and time-resolved information on the plasma, some of the theoretical and practical aspects of probe measurements in a C02-laser discharge are discussed.
