Title: Laser marking device

IPC: B23K26/06
Filed: 1999-05-31
Abstract: PROBLEM TO BE SOLVED: To miniaturize a device and reduce adjustment man-hours of an optical system. SOLUTION: A rare earth doped optical fiber 21 is used as a laser medium. The rare earth doped optical fiber 21 is maintained in the state or preliminary pumping, by using light energy from a first semiconductor laser 22A for stimulation. At marking operation, a high stimulated state is obtained by using a second semiconductor laser 22B for stimulation, a laser pulse is inputted from a semiconductor laser 10 for signal and amplified in the rare earth doped optical fiber 21, and high power laser is outputted. Since the rare earth doped optical fiber 21 can be bent, miniaturization is enabled while securing sufficient optical path length in the laser medium, e.g. by winding the optical fiber 21 around a bobbin.  Since installation of optical components, such as a mirror and a Q switch at both end portions of the laser medium is unnecessary, miniaturization of a laser oscillator part is enabled from this viewpoint also, and adjustment of the optical system can be dispensed with.

Abstract: PURPOSE: To provide a uniform antireflection coat by vapor deposition on the incident window of an infrared detector in its manufacturing process. CONSTITUTION: An infrared detector is constituted by connecting an outer cylindrical body 1 fitted with an infrared incident window 2 to an inner cylindrical body 5 mounted with an intermediate ring 7 and an infrared detecting element 4. The diameter D and full length of the outer cylindrical body 1 are set in a relation, D>=H, and the solid angle ω of the body 1 is set at a large value. At the time of manufacturing the detector, antireflection coats are vapor- deposited on both surfaces of the window 2 while the window 2 is welded to the body 1 and, thereafter, the ring 7 is welded to the body 1 and the inner cylindrical body 5 mounted with the element 4 is welded to the ring 7.  Since the solid angle ω is set at the large value, the side wall of the outer cylindrical body 1 does not obstruct the vapor deposition of the antireflection coats and the coats are uniformly deposited. In addition, the welding heat generated when the inner cylindrical body 5 is welded to the ring 7 does not affect the element 4, because the welding point is far from the element 4.
