摘要

新西伯利亚自由电子激光器(NovoFEL)连续脉冲周期辐射的激光性质表现为其多个纵向模具有良好的相干性。通过三个共振法布里-珀罗干涉仪系统过滤其中一个模式，可以创建单色激光源，足以用于典型的高分辨率太赫兹光谱(≤2⋅10-7，≤0.5 MHz)。与其他替代器件相比，该源的特点是宽调谐范围(1.5-3太赫兹)和更高的输出功率(高达100兆瓦)。

Fine Spectral Structure and Ultra-monochromatic Tunable Terahertz Radiation of the NovoFEL

Laser nature of a continuous pulse-periodical radiation of the Novosibirsk free-electron laser (NovoFEL) appears in a good coherency of its many longitudinal modes. Filtration of one of the modes by a system of three resonance Fabry-Perot interferometers allows to create laser source with monochromaticity which is sufficient for typical high-resolution THz spectroscopy (≤ 2 ⋅ 10-7, ≤ 0.5 MHz). Features of the source compared to other alternative devices are a wide tuning range (1.5–3 THz) and much more high output power (up to 100 mW).
