Abstract:
Lasing was observed at 14 wavelengths in the yellow-red part of the spectrum as a result of electronic transitions in the Te2 molecule in tellurium vapor pumped optically by He–Sr recombination laser radiation (λ = 430.5 nm). The strongest lasing lines corresponded to the BOu+ (ν' = 1–4) →XOg+ (ν'' = 36–38) transition in the 128Te2 or 130Te 126Te molecules.
