Patent number: 11016023Abstract: In an is-TPG method in which lasers having two different wavelengths are used to generate a wavelength-variable far-infrared light, a far-infrared light (TPG light) having an unstable output at a broad wavelength is also slightly generated at the same time with only one laser light. The generated is-TPG and the TPG light are converted, after passing through a specimen, to near-infrared light inside a nonlinear optical crystal for detection and are observed by a detector. The signal light output of the is-TPG light becomes unstable due to the TPG light. According to the present invention, the TPG light is removed by means of a slit and the like (filter) immediately before the specimen and is not introduced into the nonlinear optical crystal for detection. At this time, by using a change in the emission direction when the frequency of the is TPG light is changed, the filter is moved in accordance with the frequency so that only the is-TPG light passes therethrough (see FIG. 1C).Type: GrantFiled: August 22, 2017Date of Patent: May 25, 2021Assignee: Hitachi High-Technologies CorporationInventors: Mizuki Mohara, Kei Shimura, Kenji Aiko
