Abstract :
The terahertz time-domain spectroscopy system using 1030 nm wavelength femtosecond pulses generated by a Yb:KGW laser is presented. The system, employing p-InAs crystal as the emitter and GaBiAs dipole antenna as the detector, has reached the spectral width of more than 2 THz and the signal-to-noise power ratio of ~60 dB
