Abstract

The numerical modeling on pulse discharge for a high power carbon-dioxide laser was developed to describe and predict laser operating characteristics. The influence of turbulence and convection on the output of a high power fast axial flow carbon-dioxide laser is especially considered in this paper. An obvious requirement is that the pulse has a precisely specified time shape in order to obtain well-controlled optical pulse. The active medium is described by assuming a five-temperature model and balancing the quantum densities of vibrational states of the CO₂ and N₂ molecules. The conclusions are very helpful to realize pulse operation in cw carbon-dioxide lasers, especially in the laser equipment which is applied to drilling, welding and cutting.
