| 摘要: |
| 采用波长为532nm、脉宽为35ps、重复频率为10Hz的Nd:YAG锁模脉冲激光,运用前向简并四波混频技术研究芳香族有机物萘和蒽的三阶非线性光学特性,并探讨它们的非线性形成机制。结果测得萘和蒽的非线性折射率分别为3.50×10-10 esu和4.45×10-10 esu,响应时间分别为24.7ps和21.4ps。强场下的光克尔效应是萘和蒽产生非线性的主要机制。 |

| Abstract: |
| By using Nd:YAG mode-locked pulse laser (λ=532nm,f0=35ps,f=10Hz),the third-order nonlinear optical susceptibility χ(3),nonlinear refractive index coefficient n2 and response time were measured with forward degenerate four-wave mixing (DFWM).Our measurement found that the nonlinear refractive index coefficients of C10H8 and C14H10 are 3.50×10-10esu and 4.45×10-10esu,respectively,and response times are 24.7ps and 21.4ps,respectively.The mechanism for their nonlinear effect is discussed.The result shows that Aromatic Hydrocarbons are characteristic of high value n2 and short response time. |
