| 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 |
| 2 | MORPHOLOGY EVOLUTION IN PTFE AS A FUNCTION OF MELT TIME AND TEMPERATURE——Ⅰ.HIGH MOLECULAR WEIGHT SINGLE-AND MULTI-MOLECULE FOLDED CHAIN SINGLE CRYSTALS AND BAND STRUCTURES显示文摘The effect of sintering dispersed dispersion and nano-emulsion particles of high molecular weight polytetrafluoroethylene (PTFE) on a substrate as a function of 'melt' time and temperature is described. Folded chain single crystals parallel to the substrate and as ribbons on-edge (with double striations), as well as bands, are produced for longer sintering times; particle merger and diffusion of individual molecules, crystallizing as folded chain, single (or few) molecule,single crystals when 'trapped' on the substrate by cooling occur for shorter sintering times. It is suggested the observed structures develop with sintering time, in a mesomorphic melt. The structure of the nascent particles is also discussed. | J.Yang K.L.Petersen R.A.Williams P.H.Geil T.C.Long P.Xu | 2005 | Chinese Journal of Polymer Science2005，23，2： | 2 |
