摘要:

报道了一种新的有机非线性光学晶体PNPA((E)-4-((4-硝基苯亚甲基)氨基)-N-苯基苯胺)的全特性。我们讨论晶体生长和结构特征。我们给出了PNPA晶体产生太赫兹波的波长依赖性,太赫兹波谱的厚度依赖性,并测量了效率。PNPA能够产生超过NLO晶体DAST和OH-1的强THz,这些晶体多年来一直是有机高场THz发生器的标准。

英文摘要:

We report the full characterization of a new organic nonlinear optical (NLO) crystal for intense THz generation: PNPA ((E)-4-((4-nitrobenzylidene)amino)-N-phenylaniline). We discuss crystal growth and structural characteristics. We present the wavelength dependence of THz generation, the thickness dependence of the THz spectrum for PNPA crystals, and measure the efficiency. PNPA enables intense THz generation that surpasses NLO crystals DAST and OH-1, which have been the standard in organic high-field THz generators for several years.
