The dynamical properties of single crystal 1T-TaS$_{2}$ are investigated bothin commensurate charge density wave state (CCDW state) and hidden chargedensity wave state (HCDW state). We develop a useful criterion in time-domaintransmission terahertz measurement to judge whether the compound is driven intoa metastable state or still in its virgin state. An increase of terahertzconductivity by two orders of magnitude from CCDW state to HCDW state isobtained by taking account of the penetration depth mismatch, which is inagreement with reported \emph{dc} transport measurement. Upon weak pumping,only transient processes with rapid decay dynamics are triggered in both CCDWand HCDW states. We compare the conductivity increases in terahertz frequencyrange between transient and HCDW states and suggest that fluctuated metallicdomain walls may develop in the transient states.
