中文摘要:
      基于受激电磁耦子散射的太赫兹(THz)波参量振荡器是产生高能量、相干THz波的有效手段之一,实验中采用垂直晶体表面出射结构,在1.63 THz处实现了最高单脉冲能量为634 nJ的THz波输出。利用电控振镜快速改变泵浦光入射到MgO:LN晶体中的角度,实现了0.75 THz~2.81 THz范围内的快速调谐,该辐射源可以满足THz波在生物医学、太赫兹通信、环境监测等应用领域的需求。
英文摘要:
      Terahertz-wave Parametric Oscillator(TPO) based on phonon-polariton scattering is one of the promising methods for obtaining high-energy and coherent THz-wave. A high-energy THz-wave output has been experimentally demonstrated with terahertz-wave parametric oscillator based on surface-emitted configuration. The maximum THz-wave output energy of 634 nJ/pulse is obtained at 1.63 THz. The rapid tuning is achieved by rotating the injection angle of pump beam into MgO:LN crystal using an optical beam scanner. The wide tunable range is from 0.75 THz to 2.81 THz. It is excepted that such high-energy THz-wave source can meet the demands in many applications, including biomedicine, communication and environmental monitoring.
