Abstract: A laser machining method is a laser machining method for joining a first member containing a first metal and a second member containing a second metal different from the first metal, the method including a first step of forming a joint in which the first metal and the second metal are melted by performing scanning with a first laser beam, and a second step of stirring a metal structure near the joint by performing scanning, on a rear side in a scanning direction of the first laser beam, with a second laser beam having a beam diameter larger than a bean diameter of the first laser beam and having a lower power density than a power density of the first laser beam.

Abstract: A light source measurement apparatus includes an objective lens that collects light emitted from a light source having a plurality of light emission points, a first reflection attenuation filter, a second reflection attenuation filter, a condensing lens, a space filter, and a movable stage, in which the first reflection attenuation filter and the second reflection attenuation filter are disposed such that polarization directions are orthogonal to each other, in which the space filter has an opening through which light emitted from a measurement target light emission point among the plurality of light emission points is transmitted, and in which the opening has a shape in which a dimension of the measurement target light emission point in a fast direction is larger than a dimension of the measurement target light emission point in a slow direction.

Abstract: Provided herein is a solid-state battery having high volume energy density, as well as a method of manufacture of such a solid-state battery. A solid-state battery 100 is a laminate including a first collector layer 1, a positive electrode layer 2, a solid electrolyte layer 5, a negative electrode layer 4, and a second collector layer 3, in this order from the top. The solid-state battery 100 satisfies α>90°, β>90°, and α>β, where α is the angle formed in the positive electrode layer 2 by a side surface 2A of the positive electrode layer 2 and the top surface of the solid electrolyte layer 5 underlying the positive electrode layer 2, and β is the angle formed in the negative electrode layer 4 by a side surface 4A of the negative electrode layer 4 and the top surface of the second collector layer 3 underlying the negative electrode layer 4.
