“…Tremendous efforts were made to develop the fiber amplifiers during the recent decade. Indeed, the amplifier is characterized by very important and unique gain and saturation parameters [55][56][57][58][59][60] that are often used to analyze and compare different gain mediums in certain applications.…”

In this paper, the present developments of copper vapor laser technology were computational modeling and simulations methods. In most of the cases, before the experiment, the functions of electrical parameters can be predicted by the use of physical simulation codes. A single simulation model describing the discharge circuitry was introduced. By solving the equations of circuit via Runge-Kutta method, the current and voltage pulses of the discharge tube were investigated, which are in good agreement with the experimental results of the same laser.

“…Applications of CVL include the research, medicine, industry, high speed imaging, micro-machining, non-linear frequency conversion to the ultraviolet and photodynamic therapy. Furthermore, they have been used extensively as a powerful pumping source for dye lasers by the master oscillator-power amplifier array for higher output powers and beam quality [29]- [34]. In order to increase the output power and improve the laser performance, the buffer gas is used in CVL tube that provides a discharge medium when the discharge tube reaches to the required temperature of copper vapor production.…”

In order to investigate the effect of the pressure buffer gas and frequency on the output power, a copper vapor laser with active medium length of 60 cm and bore of 16 mm has been operated and optimized using air as a buffer gas. The observed oscillatory behavior of the output power versus frequency is in good agreement with the previous reports. The measured results show the maximum output power of ~1.6W at the optimum pressure of 3.8 torr and frequency of 17 kHz. Abundance of the air and reduction of the system volume due to elimination of the gas handling system as well as the economically benefits are the advantages of the employing air as a buffer gas in the copper vapor laser operation.
