Abstract

A novel method employing a self-asynchronous optical sampling scheme based on a single, repetition frequency-tunable, femtosecond laser utilized in a THz time domain spectrometer (THz-TDS) system is presented. The system can operate in a 160-ps time window with a 100-Hz scan rate. The detection bandwidth is limited to ~100 GHz and is attributed to timing jitter of the laser pulses. Continued efforts are being done to extend the detection bandwidth by improving the signal-to noise ratio of the THz detection system and by reducing the timing jitter of the femtosecond excitation laser. This rapid-scan THz-TDS system holds promise for real world applications.
