The low-energy excitations in glasses were studied by the terahertz time-domain spectroscopy (THz-TDS). The coherent THz radiation by a femto-second pulse laser enables the determination of the real and the imaginary parts of complex dielectric constants in the frequency range between 0.3 and 2.4 TH
