本文介绍了一种在电子储存环中产生稳态、宽带、相干、明亮远红外辐射的新技术，适用于远红外光谱学。在5 ~ 40 cm（-1）范围内，远红外辐射功率比普通非相干同步辐射功率增加100000。与标准汞弧灯相比，该光源的亮度高达1000倍。在同步辐射光源BESSY的“低α”光学模式中，通过束团缩短和非高斯束团变形产生相干同步辐射。
A new technology for generating steady state, brilliant, broadband, coherent, far-infrared (FIR) radiation in electron storage rings is presented, suitable for FIR spectroscopy. An FIR power increase of up to 100 000 compared to the normal, incoherent synchrotron radiation in the range of similar to5 to similar to40 cm(-1) could be achieved. The source is up to 1000 times more brillant compared to a standard Hg arc lamp. The coherent synchrotron radiation is produced in a "low alpha" optics mode of the synchrotron light source BESSY, by bunch shortening and non-Gaussian bunch deformation.
