Sažetak
Laser ablation of solid lithium, sodium, potassium and lithium-sodium alloy was performed using 308 nm excimer laser at fluences close to 1 Jcm$^{-2}$ . Frequency and time resolved A-X and B-X electronic transitions of $^{6, 7}$Li$_{2}$, Na$_{2}$, LiNa and K$_{2}$ respectively, were observed. Lithium atom and 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.
