| 1 | Engineered quasi-phase-matching for laser techniques[Invited]显示文摘The quasi-phase-matching(QPM)technique has drawn increasing attention due to its promising applications in areas such as nonlinear frequency conversion for generating new laser light sources.In this paper,we will briefly review the main achievements in this field.We give a brief introduction of the invention of QPM theory,followed by the QPM-material fabrication techniques.When combing QPM with the solid-state laser techniques,various laser light sources,such as single-wavelength visible lasers and ultraviolet lasers,red–green–blue three-fundamentalcolor lasers,optical parametric oscillators in different temporal scales,and passive mode-locking lasers based on cascaded second-order nonlinearity,have been presented.The QPM technique has been extended to quantum optics recently,and prospects for the studies are bright. | X.P.Hu P.Xu S.N.Zhu | 2013 | Photonics Research2013，1，4： | 8 |
