〈331〉晶向ZnTe单晶的太赫兹辐射及探测
Radiation and detection of terahertz pulse in〈331〉 oriented ZnTe single crystal
【摘要】 通过Te熔剂方法生长出〈331〉晶向的ZnTe体单晶,利用X射线衍射和红外透射显微技术对材料进行了测试.在钛-宝石激光器的泵浦下,利用〈331〉晶向的ZnTe晶体辐射-探测到太赫兹波,激发频谱可达5 THz左右.〈331〉晶向的ZnTe晶体表现出良好的太赫兹辐射性能.
【Abstract】 〈331〉 oriented ZnTe crystals are grown by Te-solution method and the crystals are investigated by X-ray diffraction(XRD) and infrared transmission microscope technique.The 〈331〉 oriented ZnTe crystals pumped by Ti:Sapphire laser,are emitted and detected THz width about 5 THz.The〈331〉 oriented ZnTe crystals grown by Te-solution method,exhibit good property of THz radiation.
