Previous issue date: 6"Dual-comb spectroscopies have great potential for high-resolution molecular and atomic spectroscopies, thanks to the broadband comb spectrum consisting of dense narrow modes\footnote{A. Nishiyama, S. Yoshida, Y. Nakajima, H. Sasada, K. Nakagawa, A. Onae, K. and Minoshima, Opt. Express 24, 25894 (2016).}. In this study, we apply the dual-comb system to Doppler-free two-photon absorption spectroscopy. The outputs of two frequency combs excite several two-photon transitions of rubidium\footnote{A. Hipke, S. A. Meek, T. Ideguchi, T.W. H\""{a}nsch, and N. Picqu\'{e}, Phys. Rev. A 90, 011805(R) (2014).}, and we obtained broadband Doppler-free spectra from dual-comb fluorescence signals. The fluorescence detection scheme circumvents the sensitivity limit which is effectively determined by the dynamic range of photodetectors in absorption-based dual-comb spectroscopies. Our system realized high-sensitive, Doppler-free high-resolution and broadband atomic spectroscopy._x000d_

A part of observed spectra of 5S - 5D transition is shown in the figure. The hyperfine structures of the = 1 - = 3,2,1 transitions are fully-resolved and the spectral widths are approximately 5 MHz. The absolute frequency axis is precisely calibrated from comb mode frequencies which were stabilized to a GPS-disciplined clock._x000d_

FORMATION OF CARBON INTERPHASE ON POLYCRYSTALLINE AND AMORPHOUS SiC FIBERS IN SiC/SiC COMPOSITES BY ELECTROPHORETIC DEPOSITION
No full textContinuous silicon carbide fiber-reinforced silicon carbide matrix (SiC/SiC) composites have been recognized as key materials for aerospace industries, high-temperature gas turbines and future nuclear and fusion applications because they show a pseudo-ductile fracture behavior and excellent fracture tolerance. Fiber/matrix interfaces act as an important role for toughening and strengthening SiC/SiC composites. Currently, carbon or hexagonal-boron nitride has been formed on SiC fibers as the interphases, and these interphases have been generally formed by chemical vapor infiltration (CVI), chemical vapor deposition (CVD) or solution-coating/pyrolysis process. However, these processes generally require long manufactuiring time and complicated apparatuses, and they use toxic, flammable or combustible reactant gases, resulting in much higher production cost and an increase in environmental load. Present authors paid attention to EPD process to form interphases on SiC fibers in SiC/SiC composites and demonstrated that EPD process was effective to form homogeneous C-interphase on SiC fibers [1-5]. In this study, EPD was applied for carbon interphase formation on polycrystalline (electric conductive) and amorphous (low electric conductive) SiC fibers in SiC/SiC composites, and microstructure and mechanical properties of the SiC/SiC composites were evaluated. From TEM micrograph of carbon interphase on the polycrystalline SiC fiber in the SiC/SiC composite formed by EPD, it was observed that flaky carbon particles were deposited parallel to the SiC fiber. Carbon has a layered structure and the layers bonded by weak van der Waals forces enable a low friction coefficient. As a result, the SiC/SiC composites with carbon interphases showed excellent mechanical properties with a pseudo-ductile fracture behavior. For amorphous SiC fibers, thin electric conductive polymer was coated on the amorphous SiC fibers, and carbon interphase formation was successfully achieved by EPD. The SiC/SiC composites reinforced with the carbon-coated amorphous SiC fibers also showed pseudo-ductile fracture behavior.

Lett. 94, 093306 (2009) and may be found at https://doi.org/10.1063/1.3089846.Position sensitive lasing with continuous wavelength tunability and emission in the cell-plane direction is demonstrated from a photopolymerized cholesteric liquid crystal film. The device has a gradually dilating helix lying in the cell-plane direction and is fabricated by applying a vertical electric field in a conventionally rubbed wedge cell while cooling the sample from the isotropic phase. Tuning range of ~ 100 nm is achieved by translating the device with respect to the pump beam. Photopolymerizable materials are especially useful in this configuration since a freestanding film, not requiring any external voltage to maintain the molecular ordering, can be prepared
