The invention provides a light path alignment method for detecting a bonding surface of an end face of a laser batten, belongs to the field of quality detection of the laser batten, and particularly relates to the light path alignment method for detecting the bonding surface of the end face of the laser batten. When optical detection is carried out on a laser slab, it is crucial to ensure that a detection light beam enters at a reasonable angle, and when the optical fiber white light interference measuring device is used for laser slab end face bonding surface detection, a perfect light path alignment method is provided, and the inclined end face angle of the laser slab is obtained according to a rotating control table; and a rough value of an incident angle of an optical path during end face bonding surface detection is obtained by matching with simulation analysis of ray tracing simulation software, then coarse adjustment and fine adjustment of the optical path are respectively realized through visual red l
