Abstract
A system for shaping a beam and adjusting a beam energy density includes a laser source, a collimator mirror, a spatial light modulator, an X-direction mirror, a focusing assembly, and a Y-direction mirror. The spatial light modulator includes a binary grating and a mask which are disposed in sequence. A laser beam emitted by the laser source sequentially passes through the collimator mirror, the spatial light modulator, the X-direction mirror, the focusing assembly, and the Y-direction mirror, the laser beam is shaped by changing a diffraction period of the binary grating, an energy density distribution of the laser beam is changed by adjusting a grating density of the mask, and the X-direction mirror and the Y-direction mirror are used for a dynamic scanning movement of the laser beam.
