The invention discloses a single-lamp single-rod double-cavity light path system for a laser cutting machine. The light path system comprises a red lamp indicator, a total reflective mirror, light-gathering cavities, a semi-reflective mirror, a water-cooled beam-expanding mirror and a cutting head which are arranged in sequence. The light-gathering cavities comprise the first light-gathering cavity and the second light-gathering cavity. A first xenon lamp is arranged at one end of the first light-gathering cavity, and a first crystal rod is arranged at the other end of the first light-gathering cavity. A second xenon lamp is arranged at one end of the second light-gathering cavity, and a second crystal rod is arranged at the other end of the second light-gathering cavity. The cutting head comprises a head body, a 45-degree total reflective mirror, a focusing mirror, a protecting mirror and a nozzle, wherein the 45-degree total reflective mirror, the focusing mirror, the protecting mirror and the nozzle are connected to the head body in sequence. According to the single-lamp single-rod double-cavity light path system for the laser cutting machine, the mode of double light-gathering cavities is adopted, and the laser power can be increased by fifty percent when the same power is adopted by a laser power source, so that the output power of the equipment is increased, and the cutting capacity is improved.
