FLAT WAVEGUIDE-TYPE LASER DEVICE |
| 摘要 |
A configuration is provided with a laser medium 1 of a refractive index nc that is an isotropic medium and includes an upper surface and a lower surface, where at least one of the upper surface and the lower surface is bonded with a cladding 2 having a refractive index satisfying a relationship of no<nc<ne or ne<nc<no. This allows selective output of only polarized light generated by a refractive index in the cladding 2 smaller than the refractive index nc at a desired wavelength (e.g. 1535 nm) which can be implemented by using the isotropic medium. |

1. A flat waveguide-type laser device, comprising:
an isotropic medium of a flat plate shape for transmitting a laser beam incident from a side surface thereof; and a cladding bonded to at least one of an upper surface and a lower surface of the isotropic medium, the cladding including a birefringent crystal having two different refractive indexes in two polarization directions perpendicular to a light axis that is parallel to a traveling direction of the laser beam in the isotropic medium, and the isotropic medium including a material having a refractive index between the two different refractive indexes in the two polarization directions in the cladding. |
