Time-resolved Fourier transform infrared spectroscopy} \textbf{369}, 293 (2003).} was applied for observations of emission spectra from Nd:YLF laser ablation products. A high-repetition rate laser (Photonics Industry DM10-527, 2.5 kHz) with 1-2 mJ output power was focused on a rotating rod of metal and carbon mounted on a linear actuator. The infrared emission spectra from Fe, Cu, Zn, and Al atoms were observed in the 2.5-5 $\mu$m region with a time profile showing maximum emission intensity in 3-5 $\mu$sec after a laser shot. The time profile was explained by diffusion process. The observed emission spectrum from iron ablation in the 2500 cm$\mathrm{<mrow\; data-mjx-texclass="ORD">-1</mrow>}$ region agrees very well with solar absorption spectrum, where new lines have been detected in the present experiment in addition to the lines observed from a hollow cathode discharge} \textbf{94}, 221 (1994).}. When O$2$ was added to the carbon ablation, emissions from vibrationally excited CO was observed with a vibrational temperature of $\sim$12300~K. Based on the observed time profiles, relaxation processes will be discussed.
