The invention provides a gas-liquid spray jet cooling system and method for assisting laser processing, and the system comprises a hydraulic system, an ultrasonic atomization system, an air pressure system, a gas-liquid atomization system, a Laval tube, a light transmission system and an aspherical lens system, the hydraulic system is connected with the ultrasonic atomization system, achieves the first atomization of liquid, and enables the liquid to enter the gas-liquid atomization system; the air pressure system provides any gas to enter the gas-liquid atomization system; the gas-liquid atomization system achieves secondary atomization of gas and liquid and enables the gas and the liquid to flow into the Laval pipe. And the light transmission system and the aspherical lens system realize laser transmission focusing. According to the gas-liquid spray jet cooling system and method for assisting laser machining, the gas-liquid mixing proportion can be adjusted and controlled at will, evenly-mixed micron-sized
