In this study, the design of a low power gold vapor laser is presented. The laser tube is an alumina ceramic of cylindrical shape, having the length of 58cm and the inner bore diameter of 11mm. The maximum applied DC voltage is 4.2kV, and the average current is ~ 390mA. The system is operating at the pulse repetition rate of 18.2 kHz, with 40 mbar neon gas pressure. The maximum measured output power in sealed off and gas flow conditions are 710 and 450mW, respectively. The operational behavior of the present system has been compared with that of a copper vapor laser of the same dimensions, showing that the power efficiency is much lower in the case of the gold vapor laser. While both systems have similar time behavior and introducing similar response to the operational gas pressure, it seems, however, the laser output powers versus the pulse repetition rate are different in each laser. The measured output power versus the neon gas pressure has a maximum at 60 mbar gas pressure with a cutoff which occurs at 170 mbar.
