【摘要】 同时利用脉冲和连续波运转两种方法。测量了铷激射器中铷原子由碰撞导致的在基态子能级间的弛豫率和光抽运率,得到了相互一致的效果。考察了较密原子蒸汽时总弛豫率和先抽运率与原子密度的关系,给出由了振动阈附近的激射器频率推算原子密度的新方法。更多还原

【Abstract】 The collisional relaxation and pumping rates of rubidium atoms were measured under pulse and contiunous operations of the rubidium maser and consistent results were obtained. The dependencies of total relaxation and A mpupingrates on atomic density were examined for relatively dense vapor, method of evaluating atomic density from maser freqency near oscillation threshold was given.更多还原
