  • Patent number: 9197029
    Abstract: In a laser device, a control range of focal distance of a generated thermal lens is broadened and reliability is improved. A mode control waveguide-type laser device includes: a planar laser medium having a waveguide structure in a thickness direction of a cross section perpendicular to an optical axis, for generating gain with respect to laser light; a cladding bonded onto the laser medium; and a heat sink bonded onto the laser medium. The laser medium generates a lens effect, and the laser light oscillates in a waveguide mode in the thickness direction, and oscillates in a spatial mode due to the lens effect in a direction perpendicular to the optical axis and the thickness direction. The refractive index distribution within the laser medium is created by generating a temperature distribution in the laser medium depending on a junction area of the cladding and the heat sink.

  • Patent number: 8842280
    Abstract: Disclosed is an analytical apparatus wherein a container is automatically transferred and the container is automatically closed with a cap member, said analytical apparatus being provided with a suitable mechanism that reliably closes the container. The analytical apparatus is provided with an optical sensor composed of at least one pair of a light source (4) and a light detector (5), which face each other with the container disposing position therebetween, and which are disposed such that the container disposing position is irradiated with light, and the analytical apparatus detects whether the container (1) is disposed or not or the absence/presence of the cap of the container, corresponding to a transmitted light quantity detected by means of the optical sensor. Thus, cap closing is prevented from being performed if there is no container, and the container is prevented from being transferred without the cap.
