Compared with the harmonic generated from atoms irradiated by counter-rotating two-color circularly polarized laser pulses, the harmonic efficiency of atoms irradiated by co-rotating two-color circularly polarized (CRTCCP) laser pulses with the same laser parameters is higher. The harmonics are generated by the multiphoton radiation transition after the bound electrons undergo a multiphoton absorption transition to a higher energy level. In addition, the variation of the harmonic efficiency with the field strength of different frequency components in the driving laser pulse is also studied. The circularly polarized harmonics with higher intensity can be obtained by optimizing the field strength of the driving laser field.<\/jats:p>","DOI":"10.3390\/sym14030519","type":"journal-article","created":{"date-parts":[[2022,3,3]],"date-time":"2022-03-03T20:36:30Z","timestamp":1646339790000},"page":"519","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["The High-Order Harmonic Generation from Atom Driven by Co-Rotating Laser Pulses Composed of Fundamental Frequency and High Frequency"],"prefix":"10.3390","volume":"14","author":[{"given":"Yanzuo","family":"Chen","sequence":"first","affiliation":[{"name":"Institute of Atomic and Molecular Physics, Jilin University, Changchun 130012, China"},{"name":"Jilin Provincial Key Laboratory of Applied Atomic and Molecular Spectroscopy, Jilin University, Changchun 130012, China"}]},{"given":"Xuxu","family":"Shen","sequence":"additional","affiliation":[{"name":"Institute of Atomic and Molecular Physics, Jilin University, Changchun 130012, China"},{"name":"Jilin Provincial Key Laboratory of Applied Atomic and Molecular Spectroscopy, Jilin University, Changchun 130012, China"}]},{"given":"Wendi","family":"Lan","sequence":"additional","affiliation":[{"name":"Institute of Atomic and Molecular Physics, Jilin University, Changchun 130012, China"},{"name":"Jilin Provincial Key Laboratory of Applied Atomic and Molecular Spectroscopy, Jilin University, Changchun 130012, China"}]},{"given":"Suyu","family":"Li","sequence":"additional","affiliation":[{"name":"Institute of Atomic and Molecular Physics, Jilin University, Changchun 130012, China"},{"name":"Jilin Provincial Key Laboratory of Applied Atomic and Molecular Spectroscopy, Jilin University, Changchun 130012, China"}]},{"given":"Fuming","family":"Guo","sequence":"additional","affiliation":[{"name":"Institute of Atomic and Molecular Physics, Jilin University, Changchun 130012, China"},{"name":"Jilin Provincial Key Laboratory of Applied Atomic and Molecular Spectroscopy, Jilin University, Changchun 130012, China"}]},{"given":"Yujun","family":"Yang","sequence":"additional","affiliation":[{"name":"Institute of Atomic and Molecular Physics, Jilin University, Changchun 130012, China"},{"name":"Jilin Provincial Key Laboratory of Applied Atomic and Molecular Spectroscopy, Jilin University, Changchun 130012, China"}]}],"member":"1968","published-online":{"date-parts":[[2022,3,3]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"1127","DOI":"10.1103\/PhysRevLett.42.1127","article-title":"Free-free transitions following six-photon ionization of xenon atoms","volume":"42","author":"Agostini","year":"1979","journal-title":"Phys.
