主　　题：pulse optical harmonic 

摘      要：This study examines the high-order harmonic radiation behavior of MgO crystals driven by combined pulses based on the numerical solution of the semiconductor Bloch *** found that compared with the monochromatic pulse,the MgO crystal can radiate a continuous harmonic spectrum with two platforms driven by the three-color combined *** reason is that under the three-color combined pulse,the electron ionization and recombination can be effectively controlled within a half-optical cycle of the laser *** this continuous spectrum,we synthesized an isolated attosecond pulse with a duration of approximately 370 *** study provides a new perspective on all-solid-state compact optical devices.
