摘要

当光脉冲的群速度与所有产生的太赫兹波长的相速度相匹配时，在具有高二阶磁化率的材料中使用相对较长的(-1 ps)光脉冲，可以通过光学整流有效地产生太赫兹辐射。我们的研究表明，有机盐DAST (4-N, n -二甲氨基-4'-N'甲基甲酰基磺酰基)已经满足了这些要求，通过对亚100 fs光脉冲的整流，DAST已经被证明是一个很好的太赫兹发射器[1]。

Velocity-matched generation of terahertz pulses in the organic crystal DAST

P Efficient generation of THz radiation through optical rectification is possible by using relatively long (-1 ps) optical pulses in materials with high second order susceptibilities when the group velocity of the optical pulse is matched to the phase velocity of all generated THz wavelengths. We show that these requirements are met by the organic salt DAST (4-N,N-dimethylamino-4'-N'methyl stilbazolium tosylate) which has already been shown to be a good THz emitter by rectification of sub-100 fs optical pulses [ I ] .
