Abstract

The possibility of frequency-resolved imaging using terahertz emission from laser filament plasma is demonstrated in the range from 1 to 10 THz. By leveraging axisymmetric terahertz emission from a DC-biased filament, the spatial and spectral properties of a multi-component object are characterized. Therefore, laser filament terahertz emission can be applied for spectroscopic imaging of objects.

激光细丝太赫兹发射频率分辨成像

在1到10太赫兹的范围内演示了利用激光丝等离子体的太赫兹发射进行频率分辨成像的可能性。通过利用直流偏置灯丝的轴对称太赫兹发射，表征了多组分物体的空间和光谱特性。因此，激光细丝太赫兹发射可以应用于物体的光谱成像。
