Calculation of standard formation enthalpy of the nitrides of alkali and alkaline-earth metal and analysis of their thermal stability

The resonance radiation trapping in alkaline-earth metal atomic lasers were investigated according to Holstein's theory. The threshold temperature, ground-state density and resonant level effective lifetime of the resonance radiation trapping were calculated for Ca, Sr, and Ba atomic vapor lasers with different tube radii.
