Moses 1 ; 1 Lawrence Livermore National Laboratory,USA. The NIF, the world’s most energeticlaser has been operational since 2009, and is nowtransitioning to an international user facility forhigh-energy-density and inertial fusion research.This paper summarizes NIF’s experimental capabilitiesand results.CTu2M.1 • 14:00Extended wavelength tunability of a picosecondpulse source by double-pass spectral filter forfiber-laser-based stimulated Raman spectral microscopy,Keisuke Nose 1 , Tatsuya Kishi 1 , YasuyukiOzeki 1,2 , Yasuo Kanematsu 1 , Kazuyoshi Itoh 1 ;1Osaka University, Japan; 2 JST-PRESTO, Japan.Broadband Yb-fiber pulses are spectrally filteredin a double-pass configuration for achieving widetunability of 300 cm -1 . The filtered pulses togetherwith Er-fiber ones were successfully used for thespectral imaging of polymer beads.ATu2N.1 • 14:00Controlling Laser Ablation inside TransparentThin Films, Kitty Kumar 2 , Kenneth K.C. Lee 1 ,Jianzhao Li 1 , Jun Nogami 2 , Nazir P. Kherani 1 , PeterR. Herman 1 ; 1 Dept. of Electrical and ComputerEngineering, University of Toronto, Canada; 2 Dept.of Materials Science and Engineering, University ofToronto, Canada. A new direction in femtosecondlaser nano-structuring of transparent dielectricfilms is presented towards ejecting thin layers andforming internal nano-voids that open new directionsin film coloring, flexible surface structuringand 3D microfluidics.QTu2O.1 • 14:00 InvitedTuning Photoinduced Charge Transfer in QuantumDot-based Hybrids by Self-assembly, MirceaCotlet 1 ; 1 Brookhaven National Laboratory, USA. Iwill discuss two examples on how self-assemblycan be used to control charge transfer betweenquantum dots and acceptor materials like conductivepolymers and fullerenes to achieve control ofproperties relevant to photovoltaic applications.ATu2L.2 • 14:30 InvitedOrion Laser Update from AWE, Andrew Randewich1 ; 1 Atomic Weapons Establishment, UnitedKingdom. The combined short and long pulseOrion laser is now operational at AWE. Thistalk will provide an update on its capabilities andachievements to date and the proposed futureprogramme of experiments.CTu2M.2 • 14:15Imaging the noncentrosymmetric structuralorganization of tissues with InterferometricSecond Harmonic Generation microscopy,Maxime Rivard 1 , Konstantin Popov 2 , MathieuLaliberté 1 , Antony Bertrand-Grenier 1 , FrançoisMartin 1 , Henri Pépin 1 , Christian P. Pfeffer 3 , CameronBrown 4 , Lora Ramunno 2 , François Légaré 1 ;1INRS-EMT, Canada; 2 University of Ottawa,Canada; 3 Ludwig- Maximilians-University Munich,Germany; 4 University of Oxford, United Kingdom.We image the relative orientation of organizedgroups of noncentrosymmetric molecules (likecollagen or myosin) at the micron scale in biologicaltissues by combining interferometry andSecond Harmonic Generation (SHG) microscopy.CTu2M.3 • 14:30 InvitedThree-dimensional Polarization and DopplerImaging of Living Tissue by Multi-ContrastOptical Coherence Tomography, Yoshiaki Yasuno1 , Young-Joo Hong 1 , Myeong-Jin Ju 1 ; 1 Univ.of Tsukuba, Japan. A principle and application ofJones matrix tomography (MT) is presented. JMTis first measures three-dimensional distributionof the Jones matrices and derives back-scatteringintensity, Doppler shift, and phase retardationfrom the Jones matrix tomography.ATu2N.2 • 14:15Optically-transparent actuators and micro-mechanicalsystems fabricated using femtosecondlasers, Yves Bellouard 1 ; 1 Eindhoven University ofTechnology, Netherlands. Non-linear laser-matterinteraction offers the possibility to structuretransparent material in three dimensions. Here, wedemonstrate that such process can be implementedfor fabricating novel type of microsystems, includingactuators transparent to visible light.ATu2N.3 • 14:30 InvitedDirect Joining and Welding with UltrashortLaser Pulses, Wataru Watanabe 1 ; 1 Natl Inst of AdvIndustrial Sci & Tech, Japan. Ultrashort laser pulsescan be used to directly join transparent substratesby localized melting and resolidification withoutany intermediate layers. I review recent advanceof welding and joining of glass substrates withultrashort laser pulses.QTu2O.2 • 14:30 InvitedOn the Origin of Efficient Photoluminescencein Silicon Nanocrystals, Daniel Hannah 1 , JihuaYang 2 , Paul Podsiadlo 3 , Maria Chan 3 , ArnaudDemortiere 3 , David Gosztola 3 , Vitali Prakapenka 4 ,George Schatz 1 , Uwe Kortshagen 2 , RichardSchaller 1,3 ; 1 Department of Chemistry, NorthwesternUniversity, USA; 2 Department of MechanicalEngineering, University of Minnesota, USA; 3 Centerfor Nanoscale Materials, Argonne National Laboratory,USA; 4 Center of Advanced Radiation Sources,University of Chicago, USA. Discrepancies existsregarding the nature of photoluminescence fromquantum-confined silicon nanocrystals. Here,using hydrostatic pressure, x-ray diffraction, andoptical spectroscopy, we provide fundamentalinsights regarding whether emission arises fromnanocrystal surface or core states.Tuesday, 11 JuneConcurrent sessions are grouped across four pages.
