First, a patterned substrate including an insulating substrate, a conductive seed layer, and an insulating layer is prepared. The seed layer is disposed on the insulating substrate, and consists of a first part having a predetermined pattern corresponding to the wiring pattern and a second part as a part other than the first part. The insulating layer is disposed on the second part of the seed layer. Subsequently, a metal layer having a thickness larger than a thickness of the insulating layer is formed on the first part of the seed layer. Here, a voltage is applied between an anode and the seed layer while a resin film containing a metal ion-containing solution is disposed between the patterned substrate and the anode and the resin film and the seed layer are brought into pressure contact. Subsequently, the insulating layer and the second part of the seed layer are removed.

Method for manufacturing wiring board

An amplification fiber which can generate a laser beam in a visible region even when a silica glass is used as a base material of a core of the amplification fiber is realized. An amplification fiber according to an embodiment of the present disclosure includes a core configured to generate a laser beam from an excitation beam in a visible region, and a cladding surrounding the core. The core is composed of a core material including Dy, one or more elements selected from Al, Ge, and P, and a silica glass.

Amplification fiber and laser beam emitting apparatus

A first fiber is connected to a first end of a third fiber doped with a rare earth element, and a second fiber is connected to a second end of the third fiber. In the third fiber doped with the rare earth element, a central portion of a core is more heavily doped with the rare earth element than a peripheral portion of the core is.

Optical fiber laser device

A reflector includes a gain fiber and a periodic refraction structure unit. The gain fiber has a core doped with a rare earth element. The periodic refraction structure unit includes a high-refractive-index region that has a predetermined width, that is formed at a predetermined spacing along an optical axis direction of the gain fiber, that is formed across an entire section of the core that is orthogonal to the optical axis of the core, and that has a first refractive index, and a low-refractive-index region that is formed adjacent to the high-refractive-index region, that has a width equal to the predetermined spacing, and that has a second refractive index lower than the first refractive index. A width dof an iperiodic structure of refractive index in the periodic refraction structure unit is given by the equation d=H&#xb7;(&#x3bb;/(2&#xb7;n))+&#x3bb;/(4&#xb7;n).
