Abstract

By using several continuous wave (CW) single longitudinal-mode semiconductor laser diodes in the red spectral region, we have excited Li2 molecule from the X 1Σ g+ state to the A 1Σu+ state (transitions: (v " = 0, J " = 19) → (v' = 4, J' = 18); (v " = 1, J " = 9) → (v' = 5, J' = 10); (v " = 2, J " = 9) → (v' = 10, J' = 10)) and observed the fluorescence of the resonance A → X lines together with collision induced lines. Comparison with theoretical simulations shows a very good agreement. The use of two or three diode lasers is discussed in view of two- or three-step excitation of Li2 molecule to the higher Rydberg or ionized molecular states.
