Determination of the optimal capacity of continuous molecular carbon dioxide

ABSTRACTSome parameters and their effects on CO2 laser output were studied in this research. This has been done through studying the effect of gases mixture pressure inside the electrical discharge tube and effect of electrical discharge current. Calculating (E/N) through molecular population using the optimum power parameters of the molecular laser CO2, was done. The theoretical value of output power and this value were compared with the practical value. It was found that the optimum operating conditions for the system were (35 mbar) as an operating pressure and (25 mA) as discharge current, where the velocity of the cooling water flow rate was . System efficiency in the optimum operating cases of CW CO2 laser reached (1.7%) and system output power was (0.765 Watts). The best value of the factor (E/N) of the system has been determined and found to be (3.42 1016 V.cm2) which is near the international calculated standard value of CO2 laser systems (4.5 1016 V.cm2).
