Webb14 apr. 2024 · THz emitters can broadly be classified into two categories (i) charge-based THz emitter and (ii) spin-based THz emitter. Most of the methods use femtosecond laser pulse to produce THz emission. Methods include photoconductive antennas, optical rectification, photoionization with intense laser pulse, etc. WebbWe achieved transient detection of the terahertz pulse time-domain waveform of the living HeLa cells. The characteristic absorption peaks were identified by Lambert-Beer law, respectively, at 0.49, 0.71, 1.04, 1.07, 1.26 and 1.37 THz. The absorbance is proportional to the cell concentration. forhos cm
