1、引言亚毫米波现在正在光谱学、射电天文学、高密度等离子体诊断学和污染问题诸方面得到应用。可以想象随着相干可调源的获得,这部分频谱将变得越来越重要,在历史上。亚毫米波已证明是特别难以产生的,因此,相对于相邻的光波和微波而言,这就阻碍了毫米波相邻的光波 1. Introduction Submillimeter waves are now being used in spectroscopy, radio astronomy, high density plasma diagnostics and pollution problems. It is conceivable that with the acquisition of coherent tunable sources, this part of the spectrum will become more and more important in history. Sub-millimeter waves have proven to be particularly difficult to produce, so this obstructs the light waves adjacent to millimeter waves relative to adjacent light and microwaves
