摘要： The present invention relates to an optical gain waveguide having excellent gain flatness in C-band, and excellent tolerance against variations of a pumping light wavelength as well, and a method of controlling the same. The optical gain waveguide includes an optical waveguide region which is doped with Er element which can be pumped by irradiating pumping light with a wavelength of 976 nm or less, or a wavelength of 981 nm or more. A population inversion of Er is optimized so that a gain variation in the C-band becomes minimum, by the irradiation of the pumping light. At this time, a relative gain variation of the optical gain waveguide, which is defined by a peak gain value and a minimum gain value in the wavelength region of 1,530 nm to 1,560 nm becomes smaller than 11.5%. In addition, in the optical gain waveguide, a width of wavelength range producing the relative gain variation smaller than 11% is 36 nm or more.

摘要： The medical catheter tube of the present invention integrally has an inner layer tube; reinforcement material layers formed by placing element wires on the inner layer tube; a marker; and an outer layer tube. The element wires, which are first and the other element wires, for forming the reinforcement material layers are synthetic resin element wires and/or metallic element wires, the first element wires are placed in the axis direction of the catheter to form the first reinforcement material layer, and the other element wires are wound in a coil form on the first reinforcement material layer, in the circumferential direction of the catheter, to cover the first reinforcement material layer. The marker is flexible to deformation. Because of the presence of the reinforcement material layer and the outer layer tube, flexural rigidity from a base section to a head section is reduced in a stepped or continuous manner.
