摘要： An optical fiber and an optical fiber device, which can suppress generation of the stimulated Brillouin scattering while maintaining large nonlinearity. The fiber includes a central core which is made of SiO2 as a main component and contains Al2O3 at concentration of 15 wt % or more. The fiber is allowed to propagate only a fundamental mode and has an absolute value of chromatic dispersion of 5 ps/nm/km or less at a predetermined wavelength. The device includes the fiber having the above composition. The fiber guides first light and second light having different wavelengths to propagate therethrough such that the first light and the second light interact with each other by a nonlinear optical phenomenon during the propagation, thus causing the fiber to output the first light or the second light modulated by the nonlinear optical phenomenon or third light newly produced by the nonlinear optical phenomenon and having a different wavelength.

摘要： A beam position monitor capable of detecting the exact position of a beam of charged particles even if the beam has a large cross sectional area with its beam center being deviated from the center of the monitor. A plurality of electrodes 4A through 4D are disposed in a vacuum chamber 3 for inducing voltages when a beam passes through the vacuum chamber. A first voltage ratio is determined based on the voltages at the respective electrodes induced by the beam to thereby detect the beam position. An antenna 10 is disposed in the vacuum chamber 3 at a beam path for inducing voltages at the respective electrodes. A second voltage ratio is determined based on the voltages at the respective electrodes induced by the antenna whereby the first voltage ratio is corrected by using the thus determined second voltage ratio. The antenna has a cross sectional area equal to or less than that of the beam.
