Abstract: A laser processing method of laser processing a workpiece made of at least one sheet of metallic foil includes: generating laser light by supplying pulsed pumping energy to a laser medium, the laser light including an optical pulse component and a continuous light component that is continuous with the optical pulse component and temporally after the optical pulse component; irradiating a surface of the workpiece with the laser light; and limiting duration of the continuous light component such that a ratio of energy of the continuous light component to energy of the optical pulse component is equal to or less than a predetermined value.

Abstract: A drawer structure, etc. of an optical fiber from an optical module is disclosed. An optical fiber drawer structure is configured by a roughly cylindrical passage through which an optical fiber passes being connected to a housing. The passage includes a sleeve connected to an outer periphery of the housing and a lid part connected to a tip side of the sleeve. The interior of the passage (sleeve) is provided with a fixing member to fix the optical fiber to the passage. A reduced diameter part and an expanded diameter part are formed in the lid part.
