Laser induced fluorescence of Li2 A 1Su+ state.
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 1Sg+ state to the A 1Su+ 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.
