We demonstrate this source applied to confocal and wide-field microscopy, as well as multiwell-plate imaging. We also report first application of a tunable supercontinuum source (TSS) to FLIM and to in situ measurements of relative excitation spectra. We are currently applying this source to hyperspectral imaging and working towards a system for acquiring the full fluorescence excitation-emission matrix. Fluorescence lifetime imaging (FLIM) can provide further information about fluorescent samples and requires a rapidly modulated or pulsed light source, in general, (tunable) ultrafast light sources, particularly in the visible, are complex and expensive and usually require a significant degree of adjustment to achieve tunability","PeriodicalId":354643,"journal":{"name":"CLEO/Europe. 2005 Conference on Lasers and Electro-Optics Europe, 2005.","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-06-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122396672","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}

In the strong coupling regime the cavity field generated by atomic scattering interferes destructively with the pump on the atoms. In this configuration atomic excitation is suppressed even for strong driving fields, while the stationary intracavity field amplitude is almost independent of the atom number. The magnitude of this interference effect depends on the detuning between laser and cavity field and on the relative atomic positions and is strongest when the atoms are ordered in a wavelength spaced lattice placed at the antinodes of the cavity mode. In this case three dimensional intensity minima are created in the vicinity of each atom. We analyze the mechanical forces in the regime where the interference condition is fulfilled, and show that the atomic pattern is mechanically stable whenever the driving frequency is red detuned with respect to the cavity frequency, irrespective of the atomic transition frequency","PeriodicalId":354643,"journal":{"name":"CLEO/Europe. 2005 Conference on Lasers and Electro-Optics Europe, 2005.","volume":"108 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-06-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122528819","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}
