The utility model discloses a YAG light path system with a stable light splitting ratio. The YAG light path system comprises a YAG laser, a quarter-wave plate, a spectroscope, a reflector, a light limiting hole and a rotary table reflection system, the reflecting mirror comprises a first reflecting mirror and a second reflecting mirror; the light limiting holes comprise a first light limiting hole and a second light limiting hole; the rotary table reflection system comprises a plurality of reflectors and is used for carrying out pointing adjustment on a light path; the quarter-wave plate 1 is arranged at the tail end of the YAG laser; laser emitted by the YAG laser sequentially passes through the quarter-wave plate, the spectroscope, the first reflector, the second reflector, the first light limiting hole, the second light limiting hole and the rotary table reflection system. According to the utility model, accurate one-by-one energy monitoring of the YAG laser is realized, all-day scanning of an emergent lig
