Abstract
An optical path structure, an optical path system, and a transfer method. The optical path structure includes a beam adjustment module configured to adjust a diameter of a laser beam and output a first beam; a beam shaping module configured to perform energy homogenization on the first beam to obtain a second beam; and a beam focusing module configured to focus the second beam and output a target light spot; the target light spot is used for irradiating a device substrate, so that a bonding material in the device substrate changes after being irradiated by the target light spot, and a target device is separated from a carrier substrate; where the bonding material is disposed between the target device and the carrier substrate.
