چکیده
در این پژوهش، یک لیزر 2CO پیوسته با جریان طولی سریع طراحی و ساخته شد که با یک مولد RF با توان بیشینه‌ی kW 1 و بسامد MHz 5/13 دمیده می‌شود. برای بهینه‌سازی کارکرد این لیزر، قطر لوله‌ی تخلیه، پهنای الکترودها، نسبت گازها و فشار آمیزه‌ی گازی آن، برای یک درازای الکترود cm 10 در یک بازه‌ی گسترده تغییر داده شدند و توان گسیلی لیزر به‌همراه بازدهی آن اندازه‌گیری و برآورد شدند. بیشینه‌ی توان گسیلی W 5/63 با بهره‌گیری از لوله‌ی تخلیه با قطر mm 26، نسبت پهنای الکترود به پیرامون لوله‌ی تخلیه‌ی 6/0، آمیزه‌ی گازی و فشار گاز mbar 90 با بازدهی الکتریکی پیرامون 3/6% به‌دست آمده است.

چکیده [English]
In this work, a continuous wave fast axial flow RF CO2 laser has been constructed, which is pumped by a 1 kW RF generator with a 13.56 MHz frequency. In order to optimize the laser performance, the diameter of the discharge tube, electrodes width, the ratio of the width of the electrode to the tube perimeter, gas ratio, and total pressure of the gas mixture was changed over a wide range for a constant electrode length of 10 cm and then the laser output power and efficiency were measured. The maximum output power of 63.5 W, implying% a 6.3 electric efficiency, was obtained for 26 mm discharge tube diameter, electrode width to discharge tube perimeter ratio of 0.6, gas mixture, and 90 mbar total pressure..
