摘要

实验研究了夹在金属锥形平行板波导窄端壁之间的薄(100 μ m厚)砷化镓晶体，在1560 nm飞秒激光的泵浦下产生太赫兹。并与自由空间中厚体砷化镓晶体的太赫兹辐射特性进行了比较。结果表明，锥形结构提高了聚焦光束泵浦的薄晶体太赫兹发射的方向性。

Terahertz Radiation from a Thin GaAs Crystal in a Metallic Tapered Parallel Plate Waveguide

Terahertz generation in a thin (100-µm thick) GaAs crystal sandwiched between the walls of a metallic tapered parallel plate waveguide at its narrow end and pumped by a 1560-nm femtosecond laser has been experimentally studied. The terahertz radiation characteristics are compared with those from a thick bulk GaAs crystal in a free space. The results demonstrate that the taper structure improves the directivity of terahertz emission from thin crystals pumped by focused optical beams.
