The synchronization of power-tuned supercontinuum generation with the time-delay of Pump/Stokes pulses in CARS hypermicroscopy allows for more effective pulse interactions — in a method we denote “spectral surfing. This, in turn, enables the single-window scanning of a broader range of CARS frequencies — from 300 cm<sup>−1</sup> to 3500 cm<sup>−1</sup>.","PeriodicalId":153736,"journal":{"name":"2017 Photonics North (PN)","volume":"46 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123470403","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}

A saturated absorption was identified as the main physical mechanism responsible for the nonlinear ultraviolet absorption in a nanosecond regime. A single-beam transmittance experiment was carried out with pulses provided by the third harmonic of a Nd:YAG laser system. A two-level model led us to estimate the ultrafast optical response of the nanoparticles. It is highlighted the potential of the sample to control nanophotonic signals.","PeriodicalId":153736,"journal":{"name":"2017 Photonics North (PN)","volume":"163 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122272535","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}
