However, the beam fanning is also very strong in the photorefractive crystal with high two-wave coupling coefficient, which corrupts greatly the optical quality of the amplified image. Recently many techniques were demonstrated to get a high-gain, low-noise amplifier, in all of which people were making an effort to get rid of the beam fanning. On contrary, here we reported a new scheme utilizing the beam fanning effect to get a noise-free, high-gain amplified image by two-wave coupling.","PeriodicalId":110649,"journal":{"name":"Photorefractive Materials, Effects And Devices Prm'93","volume":"34 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132648315","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}
