Hazardous materials like Sarin, TATP (Tri acetone tri-peroxide) and their simulants like DMMP (Dimethyl Methyl Phosphonate), Acetone, and atmospheric species were detected at 7 to 11 μm wavelength band. QE PAS technique is developed and demonstrated from a standoff distance of up to 30 meters in gaseous/vapourous and aerosols based on retro-reflector in ~2.0 ppm concentration. Hazardous biomolecules like Tryphatophan and DPA were detected on diffused aluminum adsorbed surface plate. Explosive and its simulants, TNT on adsorbed surface and DMMP, Nitrobenzene, Acetone were detected in vapour/aerosol form. A dedicated single screen, single user, user friendly Graphical User Interface (GUI) for controlling the entire system, acquisition and processing of the incoming signal and demonstration of results has been developed with the help of Laboratory Virtual Instrument Engineering Workbench (LABVIEW).","PeriodicalId":92245,"journal":{"name":"Journal of lasers, optics & photonics","volume":"21 1","pages":"1-4"},"PeriodicalIF":0.0,"publicationDate":"2016-09-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85296872","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 envisions a laser drive consisting of very many beams at an aperture and energy where the optical technology is well-developed, used in concert to create a large scale laser driver system. In this paper we describe a StarDriver–class laser with 5120 physical beamlets disposed about the target chamber in 80 evenly spaced ports, each port containing 64 beamlets, each beamlet having about ~1.5 THz of 2D SSD bandwidth and suitable phase plates, an aperture of ~65 mm, an energy of 80 J, and frequency-converted to ~351 nm. StarDriver has many beamlets at an aperture where optical technology is well-developed, and each beamlet has energy ~100 J in a several times diffraction limited beam. The ensemble of beamlets has frequency bandwidth 2%-10%, thereby providing significant control of both hydrodynamic and laser-plasma instabilities The drive at the target is ~400 kJ, has a well-behaved low L-mode spectrum, and smooth’s very rapidly, reaching an asymptotic smoothness of <1% in less than 1 ns. We also review recent results showing that the 2ωpe instability can be significantly reduced by 20 THz bandwidth.","PeriodicalId":92245,"journal":{"name":"Journal of lasers, optics & photonics","volume":"61 1","pages":"1-3"},"PeriodicalIF":0.0,"publicationDate":"2016-06-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"72761055","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}

SF was first proposed in 1965 to explain the delayed fluorescence in anthracene crystal [1]. It was further proven by the magnetic field effect on tetracene crystal [2,3]. Interest towards SF rises in recent years due to its potential applications in photovoltaics.

Concepts developed in the physics of crystalline solids can potentially be applied to the physics of photonic super crystals. While the theory of impurity bands and excitons in semiconductor crystals has been constructed in 1970-1980, an analogous theory for photonic crystals is yet to be completed. Recent experiments and theoretical investigations reveal an intense interest for polartonic structures and systems of coupled micro resonators [1], whose applications include fabrication of clockworks of unprecedented accuracy [2,3] as well as the sources of coherent irradiation. There has been a significant advance in the photonics of imperfect structures. A number of our recent works have been devoted to optical activity of imperfect photonic crystals [4] and to dispersion of exciton-like electromagnetic excitations in non-ideal lattices of coupled micro resonators [5,6].","PeriodicalId":92245,"journal":{"name":"Journal of lasers, optics & photonics","volume":"15 1","pages":"1-3"},"PeriodicalIF":0.0,"publicationDate":"2016-05-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"73241623","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}

AR. Anti-reflection nanocoatings were discussed as early as 1938. Coating with 102.8 nm thickness was applied to both sides of glass by an associate of Nobel Laureate Irving Langmuir of General Electric. The associate was Katherine B. Blodgett. She used this Nano coating to make glass form being visible (Washington Post 12-27-1938). Pure glass is found to transmit 92% of light. 99% of light was transmitted after Ms. K. B. Blodgett coated the glass. The coated pane could only be viewed using the edges per the news clip ‘Woman Scientist Discovers Coating to Make Glass Invisible’. Clocks dial faces and showcase glasses and window panes cease to be visible. Light is not reflected from any angle. This can be used in eyeglasses to keep wearers to be bothered by light reflection or stray beams from side or behind. Camera lens with 8% less reflection can be prepared. Some cameras with 3-4 of these lenses can be used to achieve a 25-35% light transmission. The chemical formula of the coating is not yet made public and the process was not on the market for commercial sale.","PeriodicalId":92245,"journal":{"name":"Journal of lasers, optics & photonics","volume":"36 1","pages":"1-3"},"PeriodicalIF":0.0,"publicationDate":"2016-05-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83999076","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}
