Abstract :
We present high-speed terahertz time-domain spectroscopy based on electronically controlled optical sampling (ECOPS). The time delay between the two laser pulses is demonstrated to be rapidly swept at a scan rate of 1 kHz on a time delay window of 77 ps. It is shown that a measurement time is shortened by a factor of 50 by using ECOPS compared to asynchronous optical sampling.
