It is shown that injection suppresses both the wave instability inherent in semiconductor and solid-state lasers and the Faraday instability arising as a result of modulation of the pump parameter. The parameters of the injection signal are found at which the transverse instabilities are effectively suppressed.","PeriodicalId":325837,"journal":{"name":"2020 International Conference Laser Optics (ICLO)","volume":"39 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":"124878812","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}
