Abstract

A spectroscopic measurement device 1 includes: a light source unit 11 for outputting pump light La and probe light Lb; a terahertz wave generation unit 21 for generating a terahertz wave T by the input of the pump light La; a terahertz wave detection unit 23 to which the terahertz wave T and the probe light Lb are input and which modulates the probe light Lb based on a refractive index that changes due to an electro-optical effect according to the input of the terahertz wave T; and a light detection unit 13 for detecting the probe light Lb modulated by the terahertz wave detection unit 23. A main body unit 2 is configured to include the light source unit 11 and the light detection unit 13. A measurement unit 3 is configured to include the terahertz wave generation unit 21 and the terahertz wave detection unit 23. The main body unit 2 and the measurement unit 3 are optically connected to each other by a polarization maintaining fiber F.
