摘要
通过严格求解麦克斯韦-布洛赫方程,研究了超短脉冲激光与硝基苯胺分子材料的非共振相互作用.研究结果表明,当脉冲激光在该分子介质中以电荷转移态的激发能的二分之一非共振传播时,脉冲激光频谱中明显地出现了二次谐波成分,显示了该分子具有较强的双光子吸收性质.
Abstract
We theoretically investigate the non-resonant interaction between ultrashort pulse laser and para-nitroaniline molecule medium by solving the full Maxwell-Bloch equations without approximation. The results show that the second-harmonic spectral component becomes stronger as the increase of the propagating distance, which indicates the high two-photon absorption properties of the molecule.
