radiation-counter tube

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.

根据Holstein理论研究了碱土金属原子激光中的共振辐射俘获效应，分别计算了Ca，Sr和Ba蒸气激光在不同半径时产生共振辐射俘获效应的阈值温度、基态粒子数密度和共振能级的有效寿命。
