## Abstract

Provided is a solar-pumped fiber laser device that includes: a first layer of a light guiding material or a fluorescent material having a circular or an elliptical planar contour with an even thickness; and an optical fiber wound around a peripheral thickness edge of the first layer, wherein the optical fiber is irradiated with light formed of solar light having entered a flat surface of the planar contour of the first layer, the solar light being scattered by the light guiding material, or with fluorescence generated by applying the solar light having entered the flat surface of the planar contour of the first layer to the fluorescent material.

## Claims

### Claim 1

A solar-pumped fiber laser device comprising:
a first layer of a light guiding material or a fluorescent material, the first layer having a circular or an elliptical planar contour with an even thickness; and
an optical fiber wound around a peripheral thickness edge of the first layer,
wherein
the optical fiber wound around the peripheral thickness edge is irradiated with light formed of solar light having entered a flat surface of the planar contour of the first layer, the solar light being scattered by the light guiding material, or with fluorescence generated by applying the solar light having entered the flat surface of the planar contour of the first layer to the fluorescent material.

### Claim 2 (depends on 1)

The solar-pumped fiber laser device according to claim 1, wherein
an additional layer of the light guiding material or the fluorescent material is added around an outer circumference of a ring of the optical fiber wound around the peripheral thickness edge of the first layer so as to configure an entire planar outer contour of the solar-pumped fiber laser device to be polygonal.

### Claim 3 (depends on 2)

The solar-pumped fiber laser device according to claim 2, wherein
the optical fiber wound around the peripheral thickness edge of the first layer is covered by a second layer of a transparent material having a higher refractive index than a refractive index of the light guiding material or a refractive index of the fluorescent material.

### Claim 4 (depends on 2)

The solar-pumped fiber laser device according to claim 2, wherein
the additional layer is the light guiding material.

### Claim 5 (depends on 2)

The solar-pumped fiber laser device according to claim 2, wherein
the additional layer is the fluorescent material.

### Claim 6 (depends on 2)

The solar-pumped fiber laser device according to claim 2, wherein
the solar-pumped fiber laser device is configured to be a unit, and a plurality of units are assembled.

### Claim 7 (depends on 1)

The solar-pumped fiber laser device according to claim 1, wherein
the first layer is the light guiding material.

### Claim 8 (depends on 1)

The solar-pumped fiber laser device according to claim 1, wherein
the first layer is the fluorescent material.
