Abstract
A single longitudinally excited CW CO2 laser, designed based on gas flow mechanism has been used for small signal gain measurements. By inserting a ZnSe stack polarizer set at Brewster angle inside the laser cavity the absorption loss at the critical condition was obtained. The small-signal gain measurements were performed under various laser operational conditions such as gas pressure and input electric power. At the same experimental conditions, the values of the saturation intensity were calculated from the output power and the measured small-signal gain values. The results are compared with those reported previously by other researchers.
