Outline of Final Research Achievements

We developed a high-efficiency optical measurement device for operation within the small bore of a high-power magnet at low temperature. For the high-efficiency measurement of light emitted from this small region, we designed and fabricated a compact confocal optics with lens focusing and tilting systems, and used a piezodriven translation stage that allows micron-scale focus control of the sample position. We designed a measurement device that uses 10 m-long optical fibers in order to avoid the influence of mechanical vibration and magnetic field leakage of high-power magnets, and we also developed a technique for minimizing the fluorescence signal of optical fibers. By using this device, we observed Raman scattering spectra of monolayer graphene on quartz glass with a high signal-to-noise ratio.
