TERAHERTZ ELECTROMAGNETIC WAVE GENERATION DEVICE, TERAHERTZ SPECTROSCOPIC DEVICE, AND METHOD FOR GENERATING TERAHERTZ ELECTROMAGNETIC WAVE

摘要

This terahertz electromagnet wave generation device is provided with a thermoelectric material layer (2) and a light source system that is configured in a manner so as to radiate a pulsed light (5) at the thermoelectric material layer (2), thus causing the generation of a terahertz wave (6) from the thermoelectric material layer (2). The thermoelectric material layer (2) includes a sloped section at which the transmission of the pulsed light changes along a certain direction. The light source system is configured in a manner so as to radiate the pulsed light (5) to the sloped section of the thermoelectric material layer (2).
