Webb22 feb. 2024 · The efficiency of terahertz (THz) pulse generation improves at longer driving wavelengths. For this reason, the use of mid-infrared (MIR) sources is more advantageous compared to visible or near-infrared systems. In this work, we investigate how single-color and two-color schemes of MIR pulses with few-cycle pulse durations compare in … WebbThe standard terahertz (THz) detection mechanism known as electro-optic sampling can be improved in sensitivity by biasing the polarization of the sampling field. In this work, we show theoretically and experimentally how weak signals can be amplified without inducing distortions. Our study identifies the influence of THz field strength, the polarization … scrooge\\u0027s mother

Webb12 dec. 2024 · The generation and coding of multi-cycle terahertz (THz) pulses offer interesting possibilities, such as frequency comb spectroscopy or ultra-fast packet communication. In contrast to the radio frequency domain, which has largely exploited packet communication, this research area is almost unexplored at THz frequencies. Webb27 apr. 2024 · Abstract We propose a scheme to generate single-cycle terahertz (THz) pulses via reflection of an optical femtosecond pulse train from a thin layer of nonlinear resonant medium. Our method is based on the coherent control of low-frequency oscillations and free induction decay in the medium. scrooge\\u0027s nephew
