摘要

我们报告了一种易于使用的太赫兹辐射源，它结合了一个工作在3.1太赫兹的QCL和一个紧凑的、低输入功率的斯特林冷却器。QCL是基于两个小波段设计的，已开发用于高输出功率和低电泵功率。包括冷却器、电源等在内，整个系统的重量不到15公斤。3.1太赫兹时的峰值输出功率为8mw。通过成像和分子光谱实验验证了该系统的适用性。

A compact THz source for imaging and spectroscopy

We report of a easy-to-use terahertz radiation source, which combines a QCL operating at 3.1 THz with a compact, low-input-power Stirling cooler. The QCL, which is based on a two-miniband design, has been developed for high output powers and low electrical pump power. The whole system weighs less than 15 kg including cooler, power supplies etc. The peak output power is 8 mW at 3.1 THz. The applicability of the system is demonstrated by imaging and molecular spectroscopy experiments.
