摘要： The transparent medium processing device comprises: a light control section 2 for performing variable control for the status of the laser beam emitted from the light source section 1, and a light status measurement section 4 for measuring the status of the laser beam inside the processing target TG. The light control section is adjusted based on the output of the light status measurement section so that the status of the laser beam inside the processing target becomes a desired status. Since the status of the laser beam inside the processing target, which is made of such a transparent medium as glass, is measured by the light status measurement section, and is fed back to the light control section, laser processing can be executed while maintaining an optimum status at a processing point inside the processing target.

摘要： A light pulse from an ultrashort pulse light source 11 is split by a beam splitter 12 and guided, to a detection medium 4, as an excitation pulse and probe pulse having respective predetermined linearly polarized states by an excitation optical system 2 and probe optical system 3, respectively. A light track region which is generated in the detection medium 4 by incidence of the excitation pulse, and in which the refractive index is changed by a nonlinear optical effect, is irradiated with the probe pulse. Of components which have passed through the detection medium 4, a probe pulse component whose polarized state has changed through the light track region is detected by a camera 53 via an analyzer 51 in a photodetection part 5. This realizes a light track observation apparatus capable of directly observing the light track of an excitation pulse.

摘要： A fluorescence component that passes through a region of a detection medium where a change in refractive index has been induced through a nonlinear optical effect produced in the detection medium by a gate pulse is observed as a fluorescence image by utilizing a change in polarization state. By observing the change in position of the fluorescence image while correlating with the change over time in the fluorescence, a fluorescence lifetime measuring apparatus is realized with which the change over time in the fluorescence, in particular the fluorescence lifetime, can be measured efficiently with high temporal resolution.

摘要： This torque limiter is configured from a ring body and a spring-form part provided in the ring body. The ring body comprises a band-form metal plate and is bent approximately into a C-shape along the circumferential direction of a motor shaft and a lock holder. The spring-form part is formed so as to be capable of radial elastic deformation. The spring-form part is configured from main protrusions arranged in a compressed state between the motor shaft and the lock holder, and from sub-protrusions arranged in a non-compressed state. Further, grease is stored in a part or all of the concavities formed by the main protrusions and the sub-protrusions.
