Special attention has been paid to questions of preparation and inlet of the SBS-mirror gas media. We give the SBS cell parameters and characteristics of various gas mixtures in a wide range of pressures and densities also including characteristics near the critical point and of liquefied gases as well. We give experimental results from investigations of processes competing with SBS at pulse lengths from 2ns to tens of microseconds when irradiated by single pulse or repetitively pulsed radiation with the pulse rate up to hundreds of kHz. The possibility of self-compensation of thermal and striction distortions in the SBS medium has been demonstrated experimentally. We have formulated criteria for selection of mixtures for SBS mirror operation under various conditions taking into account radiation self-action.","PeriodicalId":10610,"journal":{"name":"Conference on Lasers and Electro-Optics Europe","volume":"02 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"1998-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86137343","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}

However, no attempt was made to evaluate its performance for VUV generation at wavelengths longer than 0.19 μ m in this material. As a prior experiment, we have demonstrated the VUV generation at 0.1914 μ m by type-2 mixing between the fifth harmonic of a Nd:YAG laser at 1.0642 μ m and the output of a H2 Raman oscillator pumped by the same Nd:YAG laser. The phase-matching parameters tabulated in Table 1 were calculated with the Sellmeier’s equations and thermooptic constants reported in Ref.1. The 12-mm-long crystal used in this experiment was cut at θ ≃ 41 ° and ϕ =0 ° for type-2 second harmonic generation (SHG) at 0.5321 μ m. The entrance faces were polished with a flatness of λ /10 and no AR-coatings are applied for this crystal.","PeriodicalId":10610,"journal":{"name":"Conference on Lasers and Electro-Optics Europe","volume":"22 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"1998-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75276327","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}
