摘要： PROBLEM TO BE SOLVED: To provide a reflection type terahertz spectrometry system which eliminates the need to arrange a speculum at a position identical to that of an object to be measured and by which the object to be measured is not limited to solids. SOLUTION: The system is provided with an incident side optical channel 1 through which terahertz waves are transmitted, a means 2 which irradiates the object to be measured with the terahertz waves, an exit side optical channel 3, and a detecting section 4. The irradiating means has a planar interface and a refractive index larger than that of surrounding regions contacting the interface and is arranged so that total reflections of the terahertz waves occur on the planar interface. The object to be measured is arranged on the plane interface and irradiated with evanescent waves being emitted when the total reflections of the terahertz waves occur, and spectra are measured by using a spectrometric method. Terahertz waves emitted during a period when the object to be measured is not disposed on the plane interface, are used as references, thereby eliminating the need to arrange the speculum at the position identical to that of the object to be measured. Furthermore, the method of the system uses interactions between the object to be measured and evanescent waves oozing from the planar interface of the irradiating means, and therefore, the object to be measured is not limited to the solids.

摘要： PROBLEM TO BE SOLVED: To provide a terahertz wave generating apparatus and a terahertz wave generating method capable of obtaining a high-intensity terahertz wave with a simple structure.
SOLUTION: The terahertz wave generating apparatus 10 includes an excitation light source 11 and a nonlinear optical crystal 12. When excitation light 13 from the excitation light source 11 is incident on an incident plane 12c of the nonlinear optical crystal 12, an idler wave 14 and the terahertz wave 15 are generated. The nonlinear optical crystal 12 and air 16 configure an optical waveguide. The excitation light 13 propagates while being reflected with total reflection at an angle θ a plurality of times by total reflection planes 12a and 12b. The terahertz wave 15 generates a plurality of interactions in the process of the propagation in the nonlinear optical crystal 12 so that a phase matching condition of optical parametric amplification with the excitation light 13 is satisfied. Thus, the terahertz wave 15 is amplified a plurality of times and output as a high-intensity terahertz wave.

摘要： PROBLEM TO BE SOLVED: To provide a terahertz wave generating apparatus capable of generating a high-intensity terahertz wave at a low manufacturing cost.
SOLUTION: The terahertz wave generating apparatus includes an ultra-short pulse laser light source 3 generating an ultra-short pulse laser beam of a single repetition frequency and optical fibers F1 to F5 each transmitting the ultra-short pulse laser beam generated by the ultra-short pulse laser light source 3 and emitting them toward an LN crystal 15. Emission parts 13 in the optical fibers F1 to F5 are arranged in parallel to each other so that the ultra-short pulse laser beams L emitted from emission parts 13 are each sequentially shifted and radiated onto propagation line A of terahertz waves in the LN crystal 15. The optical path lengths of the transmission lines of the optical fibers F1 to F5 increase as they approach one side in the parallel arrangement direction of the emission parts 13.
