Radiation pulse is decomposed into Gaussian resonator modes. The electron dynamics and the radiation pulse are formulated self-consistently. We present numerical results in the small signal regime and the large signal trapped particle regime. In the trapped particle regime, the radiation field develops sideband, due to the particle oscillation in the ponderomotive potential well. We find that the wavelength of the amplitude modulation is approximately the pulse slippage distance. We will present the effect of the 3-D radiation field on the growth of the carrier frequency and the sideband frequencies.","PeriodicalId":436319,"journal":{"name":"Topical Meeting on Free Electron Generation of Extreme Ultraviolet Coherent Radiation","volume":"5 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":"115893226","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}

Physical vapor deposition techniques have been applied to the sequential deposition of layers of two materials having optical constants appropriate for the spectral range of interest. These layers are of extremely high uniformity and vary in thickness from less than 1 nanometer to 100 nanometers. This work follows the early efforts of Dumand and Youtz and the work of Dinkledge and Frericks. More recently Spiller and his coworkers have been working on the development of normal incidence multilayer mirrors specifically for the low energy x-ray domains.","PeriodicalId":436319,"journal":{"name":"Topical Meeting on Free Electron Generation of Extreme Ultraviolet Coherent Radiation","volume":"91 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":"116403796","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}

FEL Generation of Extreme Ultraviolet Coherent Radiation: Theoretical Aspects 极紫外相干辐射的FEL产生:理论方面

{"title":"FEL Generation of Extreme Ultraviolet Coherent Radiation: Theoretical Aspects","authors":"A. Renieri","doi":"10.1364/feg.1983.ma1","DOIUrl":"https://doi.org/10.1364/feg.1983.ma1","url":null,"abstract":"The main features of the interaction between free-electrons and electromagnetic (e.m.) waves have been deeply investigated in these last years, in connection with FEL dynamics. The first approach to the FEL topics was done in a quantum mechanical framework. In spite of this fact, the most interesting results were obtained by using completely classical approaches. This kind of treatment, which is well justified for the up to now developed FEL sources (infrared and visible radiation), can become no more adequate in the extreme UV spectral region. In this paper the validity limits of the classical approach are investigated. It is found that low electron energy operation with small wavelength pump wave may require the quantization of the electron motion, while the high energy and long pass undulator devices can be treated satisfactorily with classical mechanics. Furthermore, the coherence properties of the emitted radiation are studied. For these topics too, the classical or quantum character of the electron motion plays a crucial role. In particular, it is possible to show that, when a \"semi-classical\" treatment can be done (i.e., quantized radiation and classical electron) the e.m. field coherent states preserved by the FEL interaction are the same as the ones of standard lasers, i.e. the harmonic oscillator coherent states (Glauber states). Finally, the very short wavelength FEL operation is investigated by accounting for the limitation coming from electron beam energy spread and emittance. It comes out that recirculated FEL devices (i.e., Storage Ring FELs) may have, under this point of view, performances better than the single pass ones.","PeriodicalId":436319,"journal":{"name":"Topical Meeting on Free Electron Generation of Extreme Ultraviolet Coherent Radiation","volume":"122 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":"115513179","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}
