A phase conjugation efficiency higher than 90% was achieved. It was found that, apart from the stimulated Brillouin scattering (STBS) component, the scattered beam also contained a second component without a frequency shift. Their ratio depended on the geometry used to couple the pump beam into the nonlinear medium and its intensity. Phase conjugation was achieved as a result of STBS.","PeriodicalId":21878,"journal":{"name":"Soviet Journal of Quantum Electronics","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"1992-07-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81954113","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}

The presence of astigmatism negligibly influences the phase conjugation quality. In addition, in both cases an increase in aberrations results in a linear rise in the stimulated Brillouin scattering threshold.","PeriodicalId":21878,"journal":{"name":"Soviet Journal of Quantum Electronics","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"1992-07-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88344885","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}
