We report the observations of the excimer laser-induced dysprosium plasma. The time evolution of DyI and DyII selected resonance line intensities and line widths was studied. It is found that the time development of the plasma plume can be significantly influenced by the presence of argon backing gas. The comparison of the measurements of dysprosium atomic line widths made in vacuum and in argon shows a small influence of argon on the measured Stark line widths.
