我们开发了一个桌面源的强，窄带太赫兹脉冲通过II型差频产生的ZnTe晶体使用两个线性啁啾和正交偏振的光脉冲。脉冲能量在1-3 nJ的范围内，取决于从1到5 ps的可变脉冲持续时间。电场幅度达到10 kV/cm左右。光谱中心频率在0.3 ~ 2.5THz范围内连续可调，带宽在0.2- 0.5THz。(C)2008年美国物理学会。
We developed a tabletop source of intense, narrow band terahertz pulses via type-II difference-frequency generation in ZnTe crystal using two linearly chirped and orthogonally polarized optical pulses. The pulse energy is in the range of 1-3 nJ depending on the variable pulse duration from 1 to 5 ps. The amplitude of electric field reaches similar to 10 kV/cm. The central frequency of the spectrum is continuously tunable from 0.3 to 2.5 THz with the bandwidth at 0.2-0.5 THz. (C) 2008 American Institute of Physics.
