摘要：

We have constructed a terahertz-wave parametric oscillator (TPO) with pulse-to-pulse access to random wavelengths, using an optical beam scanner and a confocal optics system (1: 1 telescope) to vary the pump light angle of incidence. In addition, we used the TPO in a spectroscopic study of HCl gas in order to test its tunability, and confirmed that the TPO was continuously tunable from 1 to 2 THz and could rapidly access random frequencies in that range.
