摘要
Tunable high-power THz-wave radiation is achieved via a compact eudipleural THz-wave parametric oscillator.The maximum THz-wave output is 1.164 V at 1.755 THz when the pump energy is 90 mJ.In the experiments we find that the maximum output of THz-wave moves to the high frequency band as the pump energy increases and this phenomenon is reasonably explained.The polarization characteristics of the THz-wave are analyzed.
