Statistical approach in planning experiments with a copper bromide vapor laser

Abstract

We investigate the Feshbach conversion of fermionic atom pairs to condensed bosonic molecules with a microscopic model that accounts for the repulsive interactions among all the particles involved. We find that the conversion efficiency is enhanced by the interaction between bosonic molecules, while it is suppressed by the interactions between fermionic atoms and between atoms and molecules. In the adiabatic limit, the combined effect of these interactions can lead to a ceiling of less than 100% on the conversion efficiency for a narrow Feshbach resonance. Our theory agrees with the recent Rice experiment on 6 Li.

On the Application of the Multidimensional Statistical Techniques for Exploring Copper Bromide Vapor Laser

“…It total, the data from more than 300 experiments from literature have been observed (see [4][5][6] and quoted there references). Many carefully randomized samples were examined in order to cover the strong requirements of the used statistical techniques.…”

“…In papers [4,6] our main goal was to apply the factor analysis to examine the initial variables with respect to the output power Pout. To this end the correlation matrix of all variables, represented by the selected sample of data was obtained (see Table 1).…”

“…In recent papers [4][5][6] we have explored a different approach -a phenomelogical independent study, based on the experimental data. To this end a big amount of data for copper bromide laser with wave lengths 510.6 nm and 578.2 nm, obtained in Metal Vapour Lasers Department Georgi Nadjakov Institute of Sohd State Physics, Bulgarian Academy of Sciences -Sofia in the recent decades were examined (see [4][5][6] and quoted there literature). Different statistical methods, such as multidimensional factor analysis, principal components analysis, multiple regression and others were applied for studying the influence of ten basic input laser parameters on the output laser power and laser efficiency.…”

Multivariate Statistical Analysis in Planning Experiments for a New Strontium Bromide Vapour Laser

“…In the field of gas lasers and metal vapour laser they are still not widely utilized. For the first time, these techniques were used for a metal bromide vapour laser, generating in the visible and ultraviolet spectrum [9][10][11][12][13][14]. For strontium metal vapour lasers and the SrBr 2 vapour laser such investigations have not been carried out.…”

Principal component analysis of a canning determinate tomato collection in the IPGR, Sadovo – Bulgaria

“…The aim of the study was to measure the individual influence of each factor on performance change in the mass of the fruit and dry matter content in the tomato collection being evaluated through factor analysis by the method of Principal Component Analysis (PCA) [1,2,4].…”
