The absorptive nonlinear optical (NLO) response at two regimes was used for monitoring the figure of merit of glass media. The NLO response efficiency is affected by Sr<sup>2+</sup> addition. The equimolar ratio of Ba<sup>2+</sup> to Sr<sup>2+</sup> in the host glass matrix gives improved composition with the lowest value of Im(x<sup>(13)</sup>) and highest matrix rigidity.

The coarse structure of the observed interference patterns in reflected and transmitted lights are explained qualitatively within the framework of a two-ray approach. The movement of interference fringes can be treated as a manifestation of the Doppler effect because of the moving bubble walls. A method to measure a relative refractive index value for moving contiguous media by means of the Doppler shifts ratio measurement has been proposed. There is a two times discrepancy between Doppler shifts ratio value predicted theoretically and measured in the experiment. It is following from a special stimulated character of the Doppler effect at experimentally realized non-equilibrium thermodynamic conditions, that are imposed by the laser light field.","PeriodicalId":218575,"journal":{"name":"2016 IEEE 7th International Conference on Advanced Optoelectronics and Lasers (CAOL)","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121064710","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}
