The basis for this effect is the excitation of the additional Stokes optical mode and the mirror elastic mode when the optical energy stored in the main Fabry-Perot cavity mode exceeds the certain threshold. We demonstrate that in the resonance case the parametric oscillatory instability will take place at the energy stored in the cavity of about five orders smaller than one planned for LIGO-II interferometer. The presence of anti-Stokes modes can depress parametric oscillatory instability. However, it is very likely that the anti-Stokes modes will not compensate the parametric oscillatory instability completely because of the existence of the mode combinations which interact with each other quite strongly.","PeriodicalId":300417,"journal":{"name":"Advanced Optoelectronics and Lasers","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-03-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129953452","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}

A lasing medium is located in a Fourier-plane of the image, its gain profile being specially shaped, while the amplified image is illuminated by a laser beam which angular divergence is appropriately formed. Criteria for the gain shape and beam divergence are formulated. A possibility for correct amplification of binary and/or half-tone images with high efficiency of energy stored in the laser medium (up to 70%) is shown. The results are applicable for laser image projectors of systems of virtual reality, simulators, etc., providing images with high dynamic range (e.g., pictures of illuminated landing stripes, approaching car lights, etc.).","PeriodicalId":300417,"journal":{"name":"Advanced Optoelectronics and Lasers","volume":"95 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-03-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124561791","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}

It occurs since the SBS amplification coefficient does not depend on the laser field phase, and the Stokes field does not \"feel\" how the laser phase helix is twisted. Therefore the amplification coefficients of a Stokes conjugated mode and an analogous mode of opposite helicity are equal to each other. For example, in the case of a doughnut laser LG01 mode the Stokes beam consists of a random superposition of a few modes including conjugated one. For rather wide class of vortex beams (for example, in the case of a laser LG11 mode with two rings), a novel phenomenon takes place that can be called as phase transformation at SBS. Its essence is in the fact that in Stokes beam a mode with regular phase front is selected, which is orthogonal to laser mode at all. In the near-threshold SBS regime, this selected mode is close to a principal Gaussian mode. At SBS of the vortex laser beam the generation of the vortex hypersonic wave takes place in the SBS-medium so that the topologic charge in the system \"Stokes wave+hypersonic wave\" is equal to the charge of incident laser wave.","PeriodicalId":300417,"journal":{"name":"Advanced Optoelectronics and Lasers","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-03-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123813677","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}
