The invention discloses an all-solid-state yellow laser for medicine. The all-solid-state yellow laser comprises a pumping source system and a resonant cavity, wherein the pumping source system comprises a semiconductor laser and a focusing coupling lens system which are sequentially connected, the resonant cavity is a straight-line cavity and is arranged at an output end of the focusing coupling lens system, the resonant cavity comprise an input mirror, a gain medium, a yellow output mirror and an optical filter which are sequentially arranged, the gain medium is Dy:BSO, pumping light emitted from the semiconductor laser is focused in the gain medium in the resonant cavity by the focusing coupling lens system, the gain medium absorbs the pumping light, oscillation is generated in the resonant cavity to stimulate yellow laser, and the yellow laser sequentially passes through the yellow output mirror and the optical filter and is out. In the all-solid-state yellow laser, a combined mode of improving dosage concentration of active ions and increasing absorption range is adopted, a non-linear frequency conversion process is not needed, the absorption rate of the gain medium to the pumping light is effectively improved, and the stability of the all-solid-state yellow laser is improved.
