摘要

讨论了由二极管激光器和LTG-GaAs光导体组成的光外差产生的连续太赫兹辐射的绝对功率和光谱分布。得到了l-nW阶的输出辐射和30 MHz的线宽。这些值可以很容易地通过采用当前的技术来稳定二极管激光器和通过制造高光导器件来提高。

Generation of CW THz radiation by optical heterodyne with diode lasers and LTG-GaAs photoconductors

The absolute power and the spectral profile of the CW THz radiation generated by optical heterodyne with diode lasers and LTG-GaAs photoconductors is discussed. An output radiation of l-nW order and a linewidth of 30 MHz were obtained. These values can be easily improved by employing current techniques for stabilizing diode lasers and by the fabrication of high-photoconductivity devices.
