我们报告了通过电光材料LiNbO 3,LiTaO 3和二甲基氨基4-N-甲基苯乙烯基甲苯磺酸盐(DAST)的光学整流产生太赫兹辐射的可扩展性。实验中使用了一台钛宝石激光器系统,在810 nm处产生215 fs,20 mJ的脉冲。使用LiNbO 3和LiTaO 3,所产生的太赫兹电场的峰值被发现与增加的光学注量的线性比例高达60 mJ/cm 2的注量,而与DAST的峰值场在这个注量范围内的比例次线性。
We report on the scalability of generating terahertz radiation by optical rectification with the electro‐optic materials LiNbO3, LiTaO3, and dimethyl amino 4‐N‐methylstilbazolium tosylate (DAST). A Ti:sapphire laser system, producing 215 fs, 20 mJ pulses at 810 nm, was used for the experiment. Using LiNbO3 and LiTaO3, the peak of the generated terahertz electric field was found to scale linearly with increasing optical fluence for fluences up to 60 mJ/cm2, while with DAST the peak field scaled sublinearly in this fluence range.
