Generation mechanism of high-power terahertz field from the plasma induced by two color optical pulses and the applications

我们成功地从双色脉冲诱导的等离子体中产生了强度为1.4 mV/cm的太赫兹场。使用该方法。我们发展了强太赫兹光谱、光泵太赫兹探测光谱和太赫兹泵浦太赫兹探测光谱。我们将光谱应用于卤素桥联的铂配合物、半导体、半金属和金属。然后，在一些样品中观察到了非线性载流子动力学，并用SIMPLE方法成功地解释了其动力学。

We successfully generated intense terahertz field with 1.4 MV/cm from the plasma induced by two-color pulses. Using the method. we developed the intense terahertz spectroscopy, optical pump-terahertz probe spectroscopy, and terahertz pump-terahertz probe spectroscopy. We applied the spectroscopies to halogen-bridged platinum complexes, semiconductors, semimetals, and metals. Then, in some specimens, nonlinear carrier dynamics were observed, whose dynamics were successfully explained by the simple methods.
