Abstract

This laser medium unit comprises a laser medium and a holding body. The laser medium has a pair of end surfaces. When seen from a direction intersecting with the pair of end surfaces, the holding body surrounds the laser medium and holds the laser medium. When seen from the direction intersecting with the pair of end surfaces, the holding body includes a deformation-allowing part extending from the inside to the outside of the holding body. The laser medium and the holding body are in contact with each other. A region in contact with the laser medium in the holding body has a width in the direction intersecting with the pair of end surfaces, and, when seen from the direction intersecting with the pair of end surfaces, extends along a side surface of the laser medium.

Abstract

The purpose of the present invention is to provide a method for allowing a target cell to emit light, in which the target cell is present inside of a cell mass and is aimed to emit light by a fluorescent probe. The present invention provides a method for allowing the target cell to emit fluorescence comprising removing calcium ions from within the cell mass or a tissue containing the target cell and contacting the cell mass or the tissue with the fluorescent probe which emits fluorescence when contacted with or taken up into the target cell, thereby allowing the target cell present inside of the cell mass or the tissue to emit light, and thus can be used in a detection of the target cell in a sample, such as a clinical sample, in which the target cell may not be present on the surface of the sample.

Abstract

The first-stage dynode is for use in a photomultiplier tube. The first-stage dynode is provided with: a bottom wall section; and one pair of sidewall sections respectively extending toward one side from both edges of the bottom wall section in a predetermined direction. An electron emission surface is configured with a bottom surface located on one side of the bottom wall section and one pair of side surfaces located on the one side of the one pair of sidewall sections, wherein each of the side surfaces is formed as a concave curved surface when viewed in a cross-section parallel to the predetermined direction.
