Recently, the important role of bond alternation (difference in the carbon-carbon double bond and single bond lengths) in influencing the second order polarizability, β, of asymmetric conjugated dyes has been pointed out.[1] It was suggested that there is an optimal degree of alternation needed to maximize β. The connection between bond-alternation and the electronic, optical and chemical properties of conjugated molecules has also been recognized previously.[2] These studies as well as the results of prior experimental studies[3] have led us to investigate the affect of bond alternation on the third-order polarizability, γ. One aim of the present work is to gain insight into the differences between the magnitude and signs of γ for simple polyenes and cyanines. For moderate length to long polyenes, nonresonant electronic γ is positive, whereas for comparable cyanines γ is negative.","PeriodicalId":219832,"journal":{"name":"Nonlinear Optics: Materials, Fundamentals, and Applications","volume":"490 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132884070","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

For example, in hydrodynamics the arrangement of the convective cells of the Rayleigh-Bernard instability [1] constitutes a model problem for pattern formation. In optics, important advances have been recently obtained in the case of lasers [2]. In contrast, transverse pattern formation in mirrorless optical passive systems [3] is no so wellknown because of the intrinsic complexity of a system without cavity and of the fact that the first experiments were done with pulsed lasers [4]. We present here results obtained with c.w. lasers and rubidium atoms.

When the pump-laser pulsewidth is much longer than the dephasing time of the vibrational relaxation, the SRS spectrum is dominated by the vibrational mode with the maximum Raman gain. The depletion of the input-laser intensity by the SRS-buildup of the Raman mode with the largest gain prevents the SRS-buildup of other Raman modes with weaker gain. Selective feedback in a two-mirror resonator geometry was used to enhance the growth of SRS of the weaker 801 cm1 mode of cyclohexane in an optical cell by lowering the feedback for the strong 2929 cm–1 mode. In a Raman gain experiment, a Raman amplifier is used to amplify a weak seeding beam generated by a Raman oscillator or a tunable laser.","PeriodicalId":219832,"journal":{"name":"Nonlinear Optics: Materials, Fundamentals, and Applications","volume":"83 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126179610","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Jain and Lind have been reported the third-order nonlinear susceptibilities χ(8) of CdS\u0000 x\u0000 Se1-\u0000 x\u0000 -doped glasses were measured to be 10-9–10-8 esu in a degenerate four-wave mixing (DFWM) experiment and that the origin of the nonlinearity can be attributed to the generation of a short-live electron-hole plasma (band-filling effect)1.
