    "abstract": "We report the development of a fast pulse polarimeter for the application to\nquantum non-demolition measurement of atomic spin (Spin QND). The developed\nsystem was tunable to the atomic resonance of ytterbium atom and has narrow\nlaser linewidth suitable for spin QND. Using the developed polarimeter, we\nsuccessfully demonstrated the measurement of the vacuum noise, with 10^6 to\n10^7 photon number per pulse.",
