Abstract:
1. A solid-state laser lift-off apparatus, comprising: a solid-state laser, a light beam shaping lens, motors of oscillating mirrors, oscillating mirrors and a field lens, as well as a movable platform, an industrial control computer and control software; the said light beam shaping lens is under the laser; the said oscillating mirrors, the motors of oscillating mirrors and the field mirrors, the light beam shaping lens are behind the laser, shaping the laser beam from the said solid-state laser; the said motors of oscillating mirrors are in front of the said field lens, controlling the movement of the said oscillating mirrors according to the instruction of the control software to implement different light beam scanning paths, wherein the said light beam scanning paths are produced by using the motors of oscillating mirrors to drive the oscillating mirrors; the said platform is under the said solid-state laser; the said control software runs in the said industrial control computer.
