We treat this mechanism as the resonance enhanced four-wave mixing process which proceeds through the parametric transformation of two pump photons into the pair of IR and VUV photons in accordance with the energy and momentum (wave vector) conservation laws which provides the angle of the cone emission. Four-wave mixing proceeds in coherent regime when the pulse widths are shorter than the transverse relaxation times.","PeriodicalId":325837,"journal":{"name":"2020 International Conference Laser Optics (ICLO)","volume":"41 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-11-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122313274","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}
