Abstract :
We developed a stabilized laser source for high-precision, asynchronous optical sampling terahertz time-domain spectroscopy, in which individual mode-locked frequencies in the two lasers and the frequency difference between them are stabilized by two independent laser-control systems. We further applied it for THz spectroscopy of water vapor.
