The production of neutron-rich isotopes and the occurrence of neutron capturecascades via laser-driven (pulsed) neutron sources are investigatedtheoretically. The considered scenario involves the interaction of alaser-driven neutron beam with a target made of a single type of seed nuclide.We present a comprehensive study over $95$ seed nuclides in the range $3\le Z\le 100$ from $^7_3$Li to $^{255}_{100}$Fm. For each element, the heaviestsufficiently-long-lived (half life $> 1$ h) isotope whose data is available inthe recent ENDF-B-VIII.0 neutron sublibrary is considered. We identifyinteresting seed nuclides with good performance in the production ofneutron-rich isotopes where neutron capture cascades may occur. The effects ofthe neutron number per pulse, the neutron-target interaction size and thenumber of neutron pulses are also analyzed. Our results show the possibility ofobserving up to $4$ successive neutron capture events leading to neutron-richisotopes with $4$ more neutrons than the original seed nuclide. This hints atnew experimental possibilities to produce neutron-rich isotopes and simulateneutron capture nucleosynthesis in the laboratory. With several selectedinteresting seed nuclides in the region of the branching point of the$s$-process ($^{126}_{51}$Sb, $^{176}_{71}$Lu and $^{187}_{75}$Re) or thewaiting point of the $r$-process (Lu, Re, Os, Tm, Ir and Au), we expect thatlaser-driven experiments can shed light on our understanding ofnucleosynthesis.
