Abstract

Terahertz (THz) waves are an electromagnetic region which lies between microwave and lights. Since the THz waves have features of both electric wave and visible lights, novel observations are possible by using THz technologies. For the further THz application, the improvement of THz source in terms of power and bandwidth is essential. Many methods have been applied to generate THz waves. One typical method to use THz waves is THz time domain spectroscopy (THz-TDS). For the source of THz-TDS, two methods due to femtosecond pulse laser pump are famous to generate THz waves. One is the PCA, and other one is non-linear optical (NLO) crystals employing optical rectification of femtosecond laser pulses. NLO crystals have higher damage threshold compare to the PCA, then we can expect strong THz generation employing NLO crystals.
