The distributions of Ti^+ and Ti densities in laser-ablation Ti plasmas were visualized by laser-induced fluorescence imaging spectroscopy. The absolute Ti density was determined by ultraviolet absorption spectroscopy. The absolute Ti^+ density was evaluated by comparing the laser-induced fluorescence intensity from Ti^+ with that from Ti. In addition, we evaluated the total numbers of Ti^+ and Ti in plasmas by integrating the density distributions spatially. As a result, it was found that the total number of Ti^+ was higher than that of Ti in the initial stage of laser-ablation plasmas. In ambient He gas, we observed the temporal increase in the total number of Ti, indicating the gas-phase production of Ti due to neutralization of Ti^+. The increase in the total number of Ti^+ was also observed, suggesting the production of Ti^+ due to neutralization of Ti^{2+}. The present experimental results show that Ti^+ and Ti^{2+} are major species produced by laser ablation of a metal Ti target.
