We report on a study of the emission spectra of Ag vapor in a vacuum (10(-2) Torr) formed in ablation of an Ag metal target by a high-repetition rate (1.0 kHz) pulsed nanosecond ArF laser (lambda = 193 nm, output energy of 15 mJ). The time-resolved infrared emission spectrum of Ag was recorded in the 1300- to 3600-cm(-1) spectral region using the Fourier transform infrared spectroscopy technique with a resolution of 0.02 cm(-1). The time profiles of the measured lines have maxima at 5-6 mu s after a laser shot and display nonexponential decay with a decay time of 3-7 mu s. The lines reported here are given with an uncertainty of 0.0005-0.016 cm(-1). The line classification is performed using relative line strengths expressed in terms of transition dipole matrix elements calculated with the help of the Fues model potential; these calculations show agreement with the large experimental and calculated data sets available in the literature.
