We have developed a real-time terahertz time-domain polarization analyzer by using 80-MHz repetition-rate femtosecond laser pulses. Our technique is based on the spinning electro-optic sensor method, which we recently proposed and demonstrated by using a regenerative amplifier laser system; here we improve the detection scheme in order to be able to use it with a femtosecond laser oscillator with laser pulses of a much higher repetition rate. This improvement brings great advantages for realizing broadband, compact and stable real-time terahertz time-domain polarization measurement systems for scientific and industrial applications.
我们利用 80MHz 重复率飞秒激光脉冲开发了一种实时太赫兹时域偏振分析仪。我们的技术基于旋转电光传感器方法，该方法是我们最近提出并使用再生放大器激光系统进行演示的；在这里，我们改进了检测方案，以便能够将其与具有更高重复率激光脉冲的飞秒激光振荡器一起使用。这种改进为实现用于科学和工业应用的宽带、紧凑和稳定的实时太赫兹时域偏振测量系统带来了巨大的优势。
