Influence on operating characteristics of scaling sealed-off CuBr lasers in active length

Statistical analysis of the CuBr laser efficiency improvement

“…The results obtained are quite reasonable and can be qualified as valid and consistent with experimental data [2][3][4][5][6][7][8][9][10][11]. They can be associated with real physical processes contributing to laser efficiency.…”

“…For over 300 initial data on 12 variables from Refs. [2][3][4][5][6][7][8][9][10][11], a 50% random sample was obtained. The resulting sample included 157 rows, which was considered as original data.…”

“…The experimental database of the Laboratory of Metal Vapour Lasers with the Institute of Solid State Physics, Bulgarian Academy of Sciences has been used for the purpose of this statistical analysis [2][3][4][5][6][7][8][9][10]. The work is a continuation of results reported earlier [11,12].…”

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.…”

“…Lower operating temperature allows use of fused silica tube and lower out-gassing rates at this temperature supports the sealed-off operation. The other advantages of CBVL are higher pulse repetition frequency, higher wall-plug efficiency and a pseudo-Gaussian beam intensity profile that is better suited to many applications than the top-hat profile of CVL [1].…”
