“…It is covered by an alumina fiber (middle cylinder) that serves as a thermal insulator providing a temperature of 1700 • C. The outermost cylinder is made of Pyrex with varying diameter to provide the change in the insulator thickness to form three distinct thermal zones along the tube, two around 1400 • C at the ends for copper vaporization and one in the middle around 1650 • C for gold vaporization. In our study, we used the thermal calculation method and computer simulation adopted from [7,8]; the temperature curve obtained is presented in Fig. 1.…”

“…In both copper and gold vapor lasers, there is a single thermal zone with an average temperature of ∼1400 • C or 1650 • C. It is worth noting that both output powers (for green and yellow lights) depend on the temperature of the ceramic tube [6]. To achieve the optimum thermal region and 268 also to increase the length of the active media at the same temperature in the CVL tube, one can use nonuniform insulation [7,8].…”

We design and construct a three-color gold-copper-vapor laser emitting green (510.6 nm), yellow (578.2 nm), and red (627.8 nm) light. The maximum measured total average output power is 12 W under sealed-off conditions. We divide the active medium into three zones (two at both ends for copper and the central zone for gold) in order to vaporize both gold and copper simultaneously. For this purpose, we use a single type of thermal insulator to change the temperature along the medium by varying its thickness, which is the main point in our design. In addition, we carry out some experiments to distinguish the dependence of the output power on the frequency and buffer-gas pressure; the measured ratio of these three wavelengths, green : yellow : red, is 22 : 10 : 7.
