Summary:The invention discloses a rapid coupling light finding method and system of a laser. The method comprises the steps that the coupling efficiency of an optical chip and a passive optical device is calculated according to physical parameters of the optical chip and the passive optical device; drawing a relation curve of the defocusing amount and the optical power attenuation beam width and a relation curve of the defocusing amount and the coupling efficiency according to the coupling efficiency obtained through calculation; and completing coupling light finding according to the relation curve of the defocusing amount and the optical power attenuation beam width and the relation curve of the defocusing amount and the coupling efficiency. According to the rapid coupling light finding method and system of the laser, the coupling efficiency and the relation curve are calculated according to the physical parameters of the optical chip and the passive optical device, so that the z-axis can be rapidly positioned accor
