The influence of typical fabrication parameters, such as pulse energy and scan velocity, on the waveguide’s spectral characteristics is explored from 500 to 1700 nm. Tests conducted in Suprasil1 evidence a strong presence of Rayleigh scattering, hindering the production of low-loss waveguides at short wavelengths. On the other hand, optical waveguides fabricated in Eagle2000 exhibited lower insertion losses at short wavelengths, enabling the fabrication of low-loss broadband optical waveguides with a two order of magnitude higher scan velocity when compared with Suprasil1.","PeriodicalId":325279,"journal":{"name":"Fourth International Conference on Applications of Optics and Photonics","volume":"299 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-10-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121825375","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}

Among a variety of possible candidates which have been explored in recent decades (such as WIMPs and WISPs), the axions are the most promising constituents of dark matter. These hypothetical particles have been proposed to solve fundamental problems of charge- parity (CP) invariance and their discovery could therefore solve two important problems in cosmology and in particle physics. The axions, and axion-like particles, have been actively searched without success since the 80’s of the last century, using both laboratory experiments and astrophysical observations. In recent years, it became clear that the axions, if they exist, could be actively produced by intense laser pulses in magnetised and unmagnetised vacuum, and that the axion field could become unstable under the action of intense laser beams. Alternatively, the signature of axions could possibly be found in the dispersion relation of electrostatic waves in strongly magnetised plasmas, due to the formation of the axion-plasmon mode. This new mode could be excited by intense laser pulses in a plasma. In the present work, we consider different configurations leading to the excitation of axions by intense laser pulses, and consider propagation both in vacuum and in plasmas. A discussion of possible experimental arrangements, using the available laser technology is included.","PeriodicalId":325279,"journal":{"name":"Fourth International Conference on Applications of Optics and Photonics","volume":"40 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-10-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128361559","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}
