1. A dispersion management method based on non-periodic spectral phase jumps, comprising the following steps:
step 1, spatially separating a light pulse with different frequency components, and meanwhile, making the different frequency components propagate in parallel; and
step 2, enabling the light pulse with the different frequency components and propagating in parallel to be incident on a non-periodic phase jump device to obtain non-periodic spectral phase jumps, forming a phase grating effect by the non-periodic spectral phase jumps to obtain two ±1-order diffracted pulses having opposite group delays, and introducing different relative delays to light pulses with different frequency components in the two diffracted pulses by the non-periodic spectral phase jumps, thereby introducing dispersion to the diffracted pulses.
