  • Abstract
    The transverse relaxation time of the laser pumping of 133Cs atomic vaporing. Even if the temperature rises, the extension of the energy distribution of the electron is suppressed the effect of a thermal extension by the quantization and can lower the oscillation threshold to the quantum-dot structure of the VCSEL without causing the decrease in the gain to the utmost limit. The design of the system that measures the brain magnetism at 100fT level. The cause brain magnetic field from 10-13T to 10-14T or more can be detected.
