| Abstract | ||
| In this paper we introduce a modified continuous CO2 laser ( CW CO2 laser ) hence some changes in the principle constitutions were done, such that , the continuous power supply with output voltage of 12 KV and 100 mA . For the purpose of measuring the effect of temperature of laser medium on basic parameter, the system was connected to digital thermometer. The measurement of some basic parameters and its effect on the output power of laser and the selection of optimum condition for operating the system in case of operating by using three gas cylinders (CO2, N2, He) separately and the other by using gas mixture of ( He: 82%, N2: 13.5%, Co2: 4.5% ) , three factors were subjected to change , first, the change of pressure of gas mixture inside the electric discharge tube, second, the effect of changing the electric discharge current, third, the effect of changing the ratio of He gas in the gas mixture were achieved the experimental results shows that the best pressure for gas mixture to produce the laser is ( 30 mbar ) while it was ( 25 mbar ) in using each gas separately by ratios ( 10: 15: 75 )% for ( CO2, N2, He ) respectively with different discharge currents . 12 mA was found to be the best discharge current and 75% was the best ratio for He in gas mixture . The characteristics of plasma-laser CO2 was studies, the theoretical value of the output power laser were determined and compared with measured value | ||
