The invention relates to the field of the laser technology, and provides a laser beam pulse time sequence synthesizer based on diffraction gratings. The laser beam pulse time sequence synthesizer based on the diffraction gratings comprises a plurality of pulse laser sets and the gratings corresponding to the pulse laser sets, wherein when one grating moves to the work position of the corresponding pulse laser set, a synchronous control device sends an instruction to the corresponding pulse laser set and triggers the pulse laser set to output pulse laser, so that the pulse laser enters a preset main optical path under the diffraction action of the grating, and moreover, the grating does not prevent pulse laser output by other pulse laser sets from entering the main optical path when not in the work positions of the pulse. The laser beam pulse time sequence synthesizer based on the diffraction gratings integrates the spectrum synthesis technology and the mechanical time sequence synthesis technology, increases the number of synthesis paths of pulse laser and keeps good light beam quality on the premise of not reducing sub-laser wavelength intervals or the number of the diffraction gratings.
