我们报道了非线性有机结晶盐的光学整流和随后产生的亚皮秒亚毫米波辐射。当光激发波长为820 nm，脉冲持续时间为150 fs时，有机盐二甲基氨基4‐N‐甲基甲酰基甲醚的整流场大小分别比GaAs和LiTaO3晶体的整流场大小大一个数量级和两个数量级。这种有机晶体目前在我们所知道的所有天然非外部偏压材料中提供了最强烈的太赫兹辐射场。
We report optical rectification and subsequent generation of subpicosecond submillimeter‐wave radiation from a nonlinear organic crystalline salt. With optical excitation at a wavelength of 820 nm and a 150 fs pulse duration, the magnitude of the rectified field from the organic salt dimethyl amino 4‐N‐methylstilbazolium tosylate is one and two orders of magnitude larger than that from GaAs and LiTaO3 crystals, respectively. This organic crystal presently provides the most intense terahertz radiated field among all of the natural nonexternally biased materials we know.
