Synchronization effect on the small-signal gain and saturation intensity of a CuBr laser

Various buffer gas effects on amplifying parameters of a copper bromide laser

“…Therefore, to reduce the operating temperature of pure CVL, copper halides such as copper bromide are used. The operating temperature of the copper halide lasers depends on the vapor pressure of the compounds, which is about 500 °C for the copper bromide laser and is lower than the pure CVL operating temperature [5][6][7][8][9]. Two principal outputs with wavelengths of 510.6-and 578.2 nm have been obtained from a halide laser, similar to CVL ones.…”

“…The CBL MOPA systems have been utilized to different technological applications, and also the development of the MOPA system in a CBL operating at 110 W average power has been reported [15,16]. In our previous works, we used a MOPA system in the CBL, to satisfy higher output power and beam quality simultaneously [7][8][9]. The gain characteristics and temperature profile have been achieved for CBLs [9].…”

Gain radial distribution of copper bromide lasers

“…On the other hand, the master oscillatorpower amplifier (MOPA) array has been used extensively in order to determine the small-signal gain (g 0 ), and saturation intensity (E S ), as laser amplifying parameters, in metal vapor lasers (S Behrouzinia, Khorasani, Kazemi, & Mashayekhi, 2011;S Behrouzinia, Sadighi-Bonabi, Parvin, & Zand, 2004;Saeid Behrouzinia, Sadighi, & Parvin, 2003;S. M. Lima, Behrouzinia, & Khorasani, 2019;S. M. Lima, Behrouzinia, S., Salem, M.K., Elahei, M., Khorasani, K.,Dorranian, D. , (2017); Nezhad, Sajad, Behrouzinia, Salehinia, & Khorasani, 2010).…”

The optimum geometrical ratio in halide lasers

“…The problems, which make a single laser with large Fresnel number not suitable for providing high power with good beam quality, are reported (Chang, 1994). The best alternative to obtain high power with good beam quality from halide lasers, as CVLs, is the use of the master oscillator and power amplifier configuration (Aeinehvand, Behrouzinia, Salem, Elahei, & Khorasani, 2017;S Behrouzinia, Sadighi-Bonabi, Parvin, & Zand, 2004;Saeid Behrouzinia, Sadighi, & Parvin, 2003;Lima et al, 2017aLima et al, , 2017b. However, scaling to high output powers requires the active volume to be increased without detriment to another factors such as pulse repetition frequency and specific output energy, which determined the average output powers of laser.…”

“…It is desirable to have four or more resonator roundtrips during gain in order to reduce the beam divergence. The finite time for propagation of the applied field along the discharge tube will affect oscillators (Lima et al, 2017b). In this work, some home-built halide lasers have been designed with different bores and different lengths.…”
