Effects of additive hydrogen on kinetics mechanisms of CuBr lasers

Effect of addition of H2 to the He buffer gas on amplifying parameters and output power of a copper bromide laser

“…All types of particles in the active medium (19 kinds), and their kinetic process during the pulse and the relaxation period, were investigated in [22]. When H 2 is added to the active medium, H 2 not only reacts with the bromine molecule to form HBr but also interacts with other plasma components in the discharge tube.…”

Effect of addition of hydrogen to neon buffer gas of copper bromide vapor laser on its spectral and temporal characteristics

“…It was found that hydrogen changes the decay rates and the radial distribution of copper metastables in CBVL [5]. The reported studies on the effect of addition of hydrogen to neon buffer gas of the CBVL have highlighted the increase of total output power of the laser [1][2][3][4][5][6][7] however its effect on the spectral components of the output is not reported so far. The power and temporal characteristics of each spectral component of the laser are important in many applications, like sum frequency generation, dye laser pumping, etc.…”

“…The output power and efficiency of the CBVL increases by addition of small amounts of hydrogen to the neon buffer gas [2][3][4][5]. It was found that hydrogen changes the decay rates and the radial distribution of copper metastables in CBVL [5].…”
