However, these systems were limited so far to a few experimental setups in university labs. We present the first extremely compact commercially available dual-wavelength source for CARS and SRS. With a foot-print of <30cm x 50cm this alignment-free turn-key system offers tuning over the highly relevant frequency range from <500cm^-1 up to 5000cm^-1 within a few seconds without any detrimental thermal effects. The spectral width of the signals is <10cm^-1 enabling a multitude of applications.","PeriodicalId":286122,"journal":{"name":"Label-free Biomedical Imaging and Sensing (LBIS) 2021","volume":"40 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-03-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130063662","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}
