近年来,随着超快激光技术的飞速发展,太赫兹波段电磁辐射的产生、探测及其应用研究,越来越受到人们的重视．太赫兹电磁辐射是一种频率介于0．1～10 THz(波长在30μm～3 mm)之间的电磁波,是人类迄今为止尚未很好开发的最后一个电磁波谱“空白”区．这一波段物质的光学性质及其
In recent years, with the rapid development of ultra-fast laser technology, the generation, detection and application of terahertz electromagnetic radiation have drawn more and more attention. Terahertz electromagnetic radiation is an electromagnetic wave whose frequency is between 0.1 and 10 THz (wavelength between 30 and 3 mm). It is the last blank area of electromagnetic spectrum that mankind has not yet developed well. The optical properties of this band of matter and their
