Publication number: 20230144262Abstract: The present disclosure relates to the technical field of terahertz (THz) wave measurement and relates to a photo-thermo-acoustic mechanism-based power measurement apparatus and measurement method for a terahertz wave at room temperature. The apparatus includes a terahertz wave power modulation component, a photo-thermo-acoustic conversion device, and an acoustic wave measurement component. In the present disclosure, the THz absorbing substance having a photo-thermo-acoustic effect is used as the photo-thermo-acoustic conversion device. A power-modulated terahertz wave is converted into an acoustic wave pulse by means of the photo-thermo-acoustic mechanism. The acoustic wave measurement component measures the acoustic wave pulse. A peak-to-peak value of a pulse of the measured acoustic wave is proportional to the power of the terahertz wave, thereby implementing the fast broadband measurement of the terahertz wave power at room temperature.Type: ApplicationFiled: November 2, 2022Publication date: May 11, 2023Applicant: Nankai UniversityInventors: Weiwei LIU, Tingyuan WANG, Nan ZHANG, Lanjun GUO
