    An axial-flux motor using sintered iron (Fe) nano-polycrystalline body has been developed at the first time. In this study, its mechanical properties such as rotational speed, torque, and output power properties were compared with those of axial-flux motors using soft iron cores. Experimental results showed that the maximum rotational speed of the axial-flux motor using sintered Fe nano-polycrystalline was 8000 rpm with load, double that of the axial-flux motors using a soft iron core. The torques of both types of motors were around 0.01Nm with a little difference, and the axial-flux motor using sintered Fe nano-polycrystalline had double the output power while keeping torque the same. Sintered Fe nano-polycrystalline has significantly higher magnetic permeability than common iron materials. The material has lower magnetic saturation flux density. Fe nanoparticles were produced from iron oxide particles by using high-repetition laser pulse in liquid. Core inductors with this material were fabricated. Measurements of the core inductor magnetization clarified that the specific permeability of the sintered Fe nano-polycrystalline was 1 million, much higher than the 1000-2000 of soft iron.

    An energy cycle using solar power and metals has been proposed. High repetitive laser pulses are generated by a solar-pumped laser or a laser generated using solar power, and the laser pulses are irradiated to metal oxides in liquid. We can obtain reduced metal nanoparticles with this method, and solar power is effectively stored as chemical energy. We fabricated Li air fuel cells using sintered Iron or Aluminum nanopaste plates as negative electrodes. Electricity was successfully produced from these cells. The observed maximum output voltage of the Al paste Li air cell was 2.9 V when they were connected to a low load. The Fe or Al paste Li air cells are expected to become common power supplies with high-energy density and high output power.

  • Calculation on 3-Dimensional Propagation of Amplified Spontaneous Emission in a Cassegrain Type 3-Pass Amplifier. Reviewed

    The multi-pass laser amplifier has been often used as the final power amplification stage in the high peakpower laser systems. The Amplified Spontaneous Emission (ASE) at such a strongly pumped laser generally results in a parasitic oscillation that limits a high gain operation of the amplifier. The three dimensional propagation of the finite-band-width ASE from laser glasses has been calculated for a 30-m long Cassegranian 3-pass disk amplifiers of 35-cm clear aperture. The computational code includes the temporal behavier of flashlamp pumping, the gain reduction in a laser disk due to ASE generation, the long-path back-and-force propagation of ASE between Cassegranian mirrors, and the reduction effect on ASE of spatial filter installed after the amplifier. The ASE energy and its profile have been compared for the on-axis and off-axis arrangement of Cassegranian optics, and also z-pass geometries for three pass configuration. The off-axis alignment of the mirror pairs is very preferable to reduce ASE to one hundredth level than that appeared in the on-axis geometry.
