    • 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.

    • 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.

    • According to this invention, an instrument and a method for nucleic acid isolation is realized, whereby it is possible to prevent, for example, adherence of a discharged solution upon dispersion of such solution to the vicinity of a nucleic acid isolation column outlet.A light source unit and a light-receiving unit that receives totally reflected light of the photosensor 41 for detecting the fluid level are placed on a site on the side surface of the nucleic acid isolation column 35, where the photosensor can detect the fluid level corresponding to a remaining liquid volume of approximately 10 ul. In addition, the light source unit of the photosensor 41 is positioned in a manner such that incident light is totally reflected from the interface between the nucleic acid isolation column 35 and air in the nucleic acid isolation column 35 and light is allowed to be incident in the solution when reaching the interface between the nucleic acid isolation column 35 and the solution in the nucleic acid isolation column 35. The light-receiving unit of the photosensor 41 is positioned in a manner such that it receives the totally reflected light and is fixed on the upper part of the nucleic-acid-adsorptive solid phase 24. The fluid level detection sensor is in communication with a syringe-driving motor 34 via a control unit 40 such that a syringe 31 is driven upward when the fluid level reaches a predetermined level, provided that a certain volume of the liquid remains in the nucleic acid isolation column 35. Accordingly, dispersion of the dispersed liquid is prevented.
