双光子共振激发的电离复合产生受激电子辐射

Generation of stimulated electron radiation by ionizationrecombination processes following two-photonresonant excitation

文中报道利用双光子共振激发锂原子到4s态,获得了多条受激电子辐射和相干辐射,同时观察到了高于4s能级的nd,ns态(n≥4)到2p态的跃迁,以及从连续态到3s态的辐射。

By two-photon resonant exciting Li-atoms to 4 s state, a series of stimulated and coherent radiation lines were generated, also observed were the transition from continued energy-level to 3 s state. The populated mechanisms and radiation properties were discussed and it is considered that stimulated radiations from indirect-pumped energy-level were generated by ionization recombination processes following two-photon resonant excitation.
