“…The Successful metal vapor lasers survive today due to their superior features-including high average output power, pulse recurrence frequency, beam quality availability from copper vapor laser (CVL), gold vapor laser (GVL) [1,2]. One disadvantage of these types of lasers is the performance at very high temperatures in the range of 1500-1800 °C [3,4]. This is associated with some complexities in the fabrication and application of laser tube materials and their insulation structure.…”

A pair of Copper Bromide lasers in an oscillator-amplifier configuration was used to study the dependence of the small-signal gain (g 0 ), saturation energy intensity (E s ) and output power on various types of Buffer gases in CuBr vapor lasers. The amplifying parameters and output power of the system were measured at different buffer gas pressure and the optimum pressure of 11, 17 and 23 torr were obtained for He, He-Ne and Ne, respectively. The values of these parameters were different for various gases used in the gain medium. It was shown that the use of He has more efficient and output power than that of Ne or their mixed ones in CuBr lasers. The type of buffer gas used in the gain medium can affect the microscopic parameters, which in turn affects the operation and output power.

“…Hence, the halide lasers produced to overcome the problems of CVL's. The operating temperature of halide lasers (400-600 o C) depend on the vapour pressure and type of the compounds and is about 500 o C for copper bromide lasers(CBLs) (Aeinehvand, Behrouzinia, Salem, Elahei, & Khorasani, 2017;Dehghani, Khorasani, Sajad, Salehinia, & Behrouzinia, 2011;Gabay, Smilanski, Levin, & Erez, 1977;Lima, Behrouzinia, & Khorasani, 2018, 2019Lima et al, 2017;Little, 1999;Petrash, 1988) which is much lower than of the pure CVL's (1550-1700 o C) (Ashtari, Behrouzinia, Sajad, & Zand, 2011;Behrouzinia, Namdar, Zand, Barry, & Hojabri, 2006;Kazaryan, Petrash, & Trofimov, 1980;Nerheim, 1977). The other advantages of halide lasers are reduction of warm-up time for laser oscillation, which is important in commercial applications, higher pulse repetition frequency, higher wall-plug efficiency and higher beam quality (D. Astadjov et al, 1997;D.…”

In this work, a copper bromide laser with an active medium length of 58 cm and an inner diameter of 20 mm designed and constructed. He and Ne used as buffer gases. The effect of reservoir temperature, He and Ne buffer gas pressure, frequency and electrical input power on the output power investigated. The result of experiments shows that an optimum laser efficiency obtained at the electrical input power of 2.1kW and corresponding operational temperature of 510 oC. The maximum output powers, 4 and 6 W, with use of He and Ne buffer gases, were determined at pressures 11 and 24 torr, respectively.

“…The halide lasers are developed to overcome the problems of pure metal copper vapor laser (CVL). The advantages of the halide lasers are: low temperature of operation which gives simpler construction of tube, reduction of start-up time for laser oscillation from cold start, higher pulse repetition frequency, higher wall-plug efficiency, and a pseudo-Gaussian beam intensity profile that is better suited for many applications than the top-hat profile of elemental CVL (Ashtari, Behrouzinia, Sajad, & Zand, 2011;Dehghani, Khorasani, Sajad, Salehinia, & Behrouzinia, 2011;Tiwari, Mishra, Khare, & Nakhe, 2014). One way to increasing of the output power from a single laser is either by increasing the active length or by increasing the cross-section, or bore of the active medium.…”

Some halide lasers tubes with different volume were used to investigate the geometrical dependence of the output power of laser. An optimum length-to-bore ratio of about 30 was obtained, which gives maximum average output power of halide lasers. The relationship between maximum average output power and geometrical factors of lasers were deduced and compared by than that of copper vapour lasers. So, the straightforward relation was obtained for designing of halide lasers tubes.
