عنوان مقاله [English]
A pair of copper bromide lasers in an oscillator-amplifier configuration was operated to measuring the small-signal gain and saturation intensity, as amplifying parameters of the laser. The values of 0.078cm-1 and 0.07cm-1 were measured for small signal gain with buffer gases neon and helium, respectively, thus, the values of 34 and 47µJ/cm2 were measured for saturation intensity with neon and helium buffer gases, respectively. The output power of system was measured; the values of 8 and 10W were obtained with buffer gases of neon and helium, respectively. It was shown that, the use of helium has more efficient and output power than that of neon in copper bromide lasers. Hence, the optimum conditions have been obtained. The results were compared to that of copper- and gold vapor lasers. The type of buffer gas used can affect the microscopic parameters, which in turn affects the operation and output power of the laser.
