实现Na_2b^3Σ_g^+-x^3Σ_u^3辐射的新途径

A new channel for achieving Na2b3∑g+-x3∑u+ emission

本文报道了用共振泵浦Na(3P)态,通过Na(3P)+Na(3S)复合而获得Na_2(b^3∑_8^+)态粒子数布居的可能,以及用双光子共振泵浦Na(4D)态获得b^3∑_8^+-x^3∑_α^+受激发射。

This paper presents the possibility to obtain population on the b^3∑g^＋; state of Na2 by recombination of Na（3P）＋Na（3S） via resonantly pumping atomic sodium to the Na （3P） state. Stimulated emission on b^3∑g^＋-x^3∑u^3 transition in sodium vapor by two-photon resonant excitation to the Na（4D） state is also reported.
