摘要：

We experimentally demonstrate a high power nanosecond pulsed terahertz (THz)-wave parametric oscillator (TPO) by using a wide pump beam. A surface emitted cavity configuration is employed to reduce the THz absorption in MgO:LiNbO3 crystal. The THz wave can be tuned from 1 THz to 3 THz. A maximum THz output energy of 438nJ/pulse is achieved at 1.56Hz using a 4.5-mm-diameter pump beam with a pulse energy of 226mJ pump energy with the repetition of 10Hz, corresponding to the energy conversion efficiency of 1.94 x 10(-6).
