摘要

采用单片锁模激光二极管(MLLD)作为光源的太赫兹时域光谱(THz-TDS)系统具有非常紧凑和快速的潜力。然而，相敏应用要求相关测量的延迟轴精确同步。在这项工作中，我们展示了一种干涉同步方案，通过利用MLLD的高重复率，硬件工作量可以忽略不计，但精度很高。

Interferometric Time Synchronization of a Terahertz Time-Domain Spectroscopy System Driven by a Mode-Locked Laser Diode

Terahertz time-domain spectroscopy (THz-TDS) systems using a monolithic mode-locked laser diode (MLLD) as the light source have the potential to be extremely compact and fast. However, phase sensitive applications require the delay axes of related measurements to be accurately synchronized. In this work, we demonstrate an interferometric synchronization scheme with negligible hardware effort and yet high accuracy by exploiting the high repetition rate of the MLLD.
