The presence of an external static magnetic field, inhibiting scattering of the initiating electrons, did not increase the maximum laser pulse energy.","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":"72820937","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}
