Summary

Descripción general del contenido del recurso.

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  10–16 V.cm2) which is near the international calculated standard value of CO2 laser systems (4.5  10–16 V.cm2).الخلاصةجرى فی هذا البحث دراسة تأثر قدرة خرج لیزر CO2 من جراء تغییر ضغط خلیط الغازات داخل أنبوب التفریغ الکهربائی ، و تغییر تیار التفریغ الکهربائی . وجرى أیضاً حساب (E/N) من خلال تعداد الجزیئات باستخدام معلمات القدرة المثلى المکونة لمادة اللیزر الجزیئی CO2 ، والتوصل إلى القیمة النظریة لقدرة الخرج ، ومقارنة هذه القیمة مع القیمة العملیة .وقد تم التوصل إلى تحدید الظروف التشغیلیة المثلى للمنظومة المستخدمة ، فکان أفضل ضغط تشغیلی لخلیط الغازات عند القیمة ، وأفضل تیار تفریغ کهربائی عند القیمة عندما کانت سرعة انسیاب ماء التبرید ، کما وجد بان أفضل قدرة خارجة للمنظومة المستخدمة هی (0.765 W) حیث وصلت کفاءة المنظومة من خلال تشغیلها فی الظروف المثلى إلى القیمة . کما تم تحدید أفضل قیمة للعامل للمنظومة فکانت بحدود ، وهی مقاربة لأفضل قیمة نظریة لمنظومات لیزر CO2 وهی .
