摘要： Disclosed is a multi-target manipulator for a pulsed laser deposition apparatus. The multi-target manipulator for a pulsed laser deposition apparatus grows a thin film having both a high quality and a repeatability, automatizes a deposition apparatus, and economically performs a pulsed laser deposition, when a thin film is grown by using a pulsed laser deposition apparatus. The multi-target manipulator for a pulsed laser deposition apparatus includes: a driving power providing member which includes a stepping motor and a motion feedthrough thereby providing a rotation driving power to the target disk driving shaft and the target driving motor shaft; a driving power transmission and head supporting member, thereby transmitting a rotation driving power necessary for rotating both the target disk provided from the driving power providing member and the target and supporting the head of the target manipulator; and a head portion, thereby performing rotations of the target disk and the target so as to locate a target material on the focal point of the laser beam.

摘要： A micro etching system using laser ablation includes a laser generator, an optical fiber waveguide, a laser beam focusing device and a sample platform. The laser generator generates an ultraviolet beam, and the optical fiber waveguide carries the laser beam radiated from the laser generator to the material to be etched. The focusing device is provided between the laser generator and optical fiber waveguide and serves to concentrate the laser beam into the optical fiber. The sample platform controls the position of the material to be etched so that the material is etched at a predetermined angle by the beam emitted from the outlet of the optical fiber waveguide.

摘要： A coaxial connector for microwave and millimeter wave measurement can be used by attachment to a vacuum chamber for instrumentation when measuring a high frequency characteristic for various electronic devices at low temperature. The coaxial connector connects microwave instrumenting equipment to a device to be tested within vacuum chamber (e.g., so as to measure a low temperature and high frequency characteristic for a high frequency device). It includes a support plate for attachment to the vacuum chamber and a support screw to prevent the coaxial connector from rotating. The support screw is of hexagonal shape in the exemplary embodiment and is arranged to one side on the center of the support plate. A coaxial cable transmits the measured signal and is extended to pass through the center of the support plate and support screw, and a V-shape connector on each end of the cable for respectively coupling between a fixed sample stand in the vacuum chamber and the microwave instrument equipment.
