[Stimulated radiation from high-lying state of Li2 generated with multiphoton in a wide wavelength region].
The experimental results of ultraviolet diffuse-band of stimulated radiation from the high-lying state of Li2 generated with any pumping wavelength between 620.0-665.0 nm were reported in this paper. In Li2-Li system, the high-lying state of Li2 was generated by two-photon excitation, ionization recombination process and collision energy pooling process, and the ultraviolet diffuse-band radiation was stimulated. The radiation was due to the transition from one of the comparable high-lying treble states to the low-lying repelling state a 3sigma(+)u. The excitation mechanisms involved were discussed in detail.
