One-D and two-D computer models of industrial CO laser

Abstract

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.

Simulation code of high power discharge for iPhones

“…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.…”

Mutual utilization of simulation for high power application in the cloud computing environment

“…In order to analyze and predict the experiments., a variety of numerical simulation codes were developed [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17] . In recent ten years, the number of systems and users of cloud computing has been increasing.…”

Flexible laser simulator constructed in the integrated information processing environment

“…Based on these remarkable progresses in hardware and software, it is possible to compose new type of laser simulator. The authors developed a variety of simulation codes [1][2][3][4][5][6][7][8][9][10][11][12][13][14] for mainframe computers, workstations, personal computers, Macintosh computers, PDA, and cellular phones. The codes were described in Fortran, C, and Java.…”
