Laser Induced Fluorescence of Li2 A 1Sigmau+ State
By using several c.w. single longitudinal mode semiconductor laser diodes in the red spectral region we have excited Li2 molecule from the X 1?g+ state to the A 1Sigmau+ state (trasitions: 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 have been discussed in view of two or three step excitation of Li2 molecule to the higher Rydberg or ionized molecular states.
