摘要： There is obtained a laser processing method by which an excellent shape of a cut surface can be achieved and an increase in cost can be suppressed. A laser processing method includes the steps of: preparing a material to be processed; and forming a modified area in the material to be processed, by irradiating the material to be processed with laser beam. In the aforementioned step, pulsed laser beam having a continuous spectrum is focused with a lens, thereby forming a focusing line constituted by a plurality of focuses that are obtained by predetermined bands forming the continuous spectrum of the laser beam, and the material to be processed is irradiated with the laser beam such that at least a part of the focusing line is located on a surface of the material to be processed, thereby forming the modified area on an axis of the focusing line.

摘要： A non-degenerate polarization-entangled photon pair generation device (1) that efficiently and easily generates non-degenerate polarization-entangled photon pairs includes: a quantum-entangled photon pair generator (2) including a single crystal in which periodically poled structures (3a, 3b) having different periods are formed; and a light radiating unit (4) for entering light into the quantum-entangled photon pair generator (2) such that the light passes through the periodically poled structure (3a) and then through the periodically poled structure (3b). A period of the periodically poled structure (3a) is different from a period of the periodically poled structure (3b) such that a parabola indicative of a relation between an emission angle and a wavelength of a polarized photon emitted based on light incident on the periodically poled structure (3a) comes into contact with a parabola indicative of a relation between an emission angle and a wavelength of polarized photon emitted based on light incident on the periodically poled structure (3b), within an allowable range under a phase matching condition.
