TEA CO2 Laser Simulator: A software tool to predict the output pulse characteristics of TEA CO2 laser

"TEA CO2 Laser Simulator" has been designed to simulate the dynamic emission processes of the TEA CO2 laser based on the six-temperature model. The program predicts the behavior of the laser output pulse (power, energy, pulse duration, delay time, FWHM, etc.) depending on the physical and geometrical input parameters (pressure ratio of gas mixture, reflecting area of the output mirror, media length, losses, filling and decay factors, etc.).

The laser active medium consists of a CO2-N2-He gas mixture. Method of solution: Six-temperature model, for the dynamics emission of TEA CO2 laser, has been adapted in order to predict the parameters of laser output pulses. A simulation of the laser electrical pumping was carried out using two approaches; empirical function equation (8) and differential equation (9). Typical running time: The program's running time mainly depends on both integration interval and step; for a 4 ks period of time and 0.001 ks integration step (defaults values used in the program), the running time will be about 4 seconds. Restrictions on the complexity: Using a very small integration step might leads to stop the program run due to the huge number of calculating points and to a small paging file size of the MS-Windows virtual memory. In such case, it is recommended to enlarge the paging file size to the appropriate size, or to use a bigger value of integration step.
