The invention provides a solid-state hydrogen target system and a laser ion source adopting the same. The solid-state hydrogen target system comprises a gas solidifying base, a gas solidifying pit andan adsorption cover, wherein the gas solidifying pit is used as a freezing target and positioned in the central part of the gas solidifying base; the adsorption cover is arranged around the gas solidifying base, and active carbon is glued on the inner surface of the adsorption cover, wherein when a vacuum cavity where the solid-state hydrogen target system is located is in a basic vacuum degree state, and when a nozzle, namely a hydrogen outlet, aligned to the gas solidifying pit sprays pre-frozen hydrogen, the hydrogen is immediately condensated and deposited on the freezing target to form asolid-state hydrogen target; and the target surface of the solid-state hydrogen target is subjected to laser targeting, and the gasified hydrogen is quickly absorbed by active carbon, so that the basic vacuum degree of the vacuum cavity is maintained effectively, the laser targeting repetitive rate is ensured, and proton generation stability is improved.
