Investigations on neon-calcium ion resonance-metastable transition laser

The conclusion is gained that calcium ion can serve as working medium for r esonance-metestable (R-M) transition laser well enough by the analysis of i ts energy levels. Using Ne as buffer gas, an average laser power of 406mW a nd maximum power density of 6.9 mW/cm(3) are obtained in a discharge tube w ith 45cm electrode interval and 12.9 mm inner diameter. Some characteristic s of the calcium ion R-M transition laser are studied and the relations of some parameters are determined.
