Description
Laser ablation of solid lithium, sodium, potassium, and lithium-sodium alloy was performed using a 308-nm excimer laser at fluences close to 1 J cm-2. Frequency and time resolved A-X and B-X electronic transitions of 6,7Li2, Na2, LiNa and K2 respectively, were observed. Lithium atom, dimer velocities, and influence of the background gas on dimer content of the plume have been measured. The origin of dimers at high densities, with subthermal internal energy, is discussed
