Short-lived radioisotopes are of special interest for nuclear structure studies, as their characteristic provide valuable reference points for theoretical predictions far from stability. By using lasers, hyperfine transitions can be accessed, allowing direct measurement of nuclear observables. For such high-resolution spectroscopy, narrow-band pulsed lasers can be created by the pulsed amplification of a cw seed laser, keeping the amplifier’s high power and short time profile whilst acquiring the seeder’s spectral properties. Spectroscopy on exotic Ag was performed at the CRIS experiment at CERN. A tunable CW single-mode OPO was employed as injection-seed for a two-stage pulsed dye amplifier. e hyperfine splitting of the ground-state ² S_1/2 to the level ² P^O_3/2 was measured and the hyperfine coupling constants were determined. For this work, ¹¹¹,¹¹⁷Ag are presented, showcasing this laser system’s applicability for future high-resolution spectroscopy studies.
