激光抽运铯束贮存泡激射器

本文提出一种铯原子束激射器的建议,其中利用了双束激光抽运选态技术和原子贮存泡方法。用密度矩阵理论分析了振荡条件,给出了激射器的振荡功率和进泡的原子束流之间的关系式。在使用TE₀₂₁模腔和石腊作涂层的环状石英泡的情况下,计算了激射器的振荡功率、线宽和腔的填充因子,对激射器的短稳亦作了相应的估计。还给出了双原子束双隔离泡的此类激射器的设想。

A LASER OPTICALLY PUMPED CESIUM BEAM MASER WITH STORAGE BULB

In this paper a cesium beam maser is proposed in which the optically pumping state selection technique by two laser beams is used together with the atom storage bulb technique.The density matrix theory is used to analyse the maser oscillation conditions.The relation between the maser oscillation power and the flux of the atoms entering the bulb is derived.Assuming the use of a TE₀₂₁ mode cavity and a annular quartz bulb coated with Paraffin, the maser oscillation power and its linewidth as well as the filling factor of the cavity are evaluated.The expected short term stability of the maser is also given.A similar maser scheme with two atom beams and two separated blubs is presented too.
