摘要 在纳秒时域,采用相位物体(PO)Z-扫描技术研究了一种新型金属簇合物溶液的瞬态热致非线性效应.该方法的最大优点是很容易区分瞬态热致非线性折射和三阶非线性折射.本文利用POZ-扫描和传统Z-扫描研究了在8ns脉宽、不同能量激光脉冲作用下[Tp*W(μ3-S)3Cu3Py3(μ3-Br)](PF6)/DMF溶液的光学非线性.从声波方程和热传导方程出发,对实验结果进行了理论分析和数值模拟,理论值和实验结果很好的吻合.研究结果表明,样品溶液的非线性折射主要来源于瞬态热致非线性效应. The transient thermally induced nonlinearity of a novel metal cluster polymer solution was investigated by using the phase object (PO) Z-scan technique which can distinguish the transient thermal effect from the third-order nonlinear refraction easily in the nanosecond regime. We studied the optical nonlinearity of the [Tp*W(μ3-S)3Cu3Py3(μ3-Br)](PF6)/DMF solutionusing both PO Z-scan and conventional Z-scan techniques with the laser pulse width of 8 ns under different input pulses energe. Results of numerical simulations and solution of simultaneously acoustic wave equation and the diffusion equation of conduction of heat agree well with the experimental results, which shows that the nonlinear refraction of the sample is due to transient thermally induced nonlinear refraction.
