Telephone +81 471 44 8811, Telefax +81 471 44 8939 ABSTRAO Computer models have been developed for the industrial CO lasers, those are oparated by transverse dc discharge in the temperature region 1 50-200 K. The 1D (dimensional) model has been developed to analyze and predict the output performance characteristics, mainly the laser power. The flow equations are coupled with the kinetic equations of the direct excitation by electron impact in discharge, V-V (vibration to vibration) and V-R/T (vibration to rotation and translation) energy transfer by collision, and spontaneous and stimulated emission. The 2D model to analyze the spatial distribution of the gas temperature and excited molecules is now under development. The flow equations, based on the control volume method for the 2D Cartesian coordinates, are described. The time integration is performed by the SIMPLEST method.

“…The authors developed the numerical simulation codes for high power discharge excited CO lasers since 1982 [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18] . At first, large-scaled computer, so called "mainframe" was used for calculation.…”
