激光

As the laser energy increases, the probability curve of slight damage increases first and then decreases, and there will be a peak.

该峰值所对应的激光能量密度具有较好的重复性，故可作为光学薄膜重复激光损伤特性的评价方法。

By the means of experiments and numerical simulations, it is verified that speckles can be formed when nanofluids are illuminated by laser beam. First, clear speckles are formed by illuminating static nanofluids containing proper volume fraction of nanoparticles. Then, classic-scattering-model and photon-nanoparticle-collision-model are respectively established based on the wave-particle duality of light. The formation of speckles with nanofluids is simulated respectively on these two models, and the formation mechanism of speckles is figured out.

其中通过静态实验确定激光照射含有合适体积百分比纳米粒子的纳米流体可以形成清晰的散斑图；基于光的波粒二象性，分别根据光的波动性和粒子性建立了"经典散射模型"和"光子——粒子随机碰撞模型"，基于这两个模型分别对激光照射纳米流体形成散斑的过程进行了数值模拟，并对散斑的形成机理进行了解释。

Analyses show that refractive index changeinduced by thermal effect is similar to the change induced by other effects for linearabsorption,if laser pulse width is far less than the characteristic time of sample,i.e.refractive index change is directly proportional to spatial part of incident pulse laserintensity,so time averaged nonlinear refractive index can be defined.

结果表明，当激光脉冲宽度远小于被测样品的特征时间时，对于线性吸收来说，其热效应产生的折射率变化与其它效应产生的折射率变化有类似的形式，即与入射脉冲激光光强的空间部分成正比。因而可定义时间平均非线性折射率。在这种情况下，可用通常的Z-scan法进行非线性折射率及热光系数的测量，所得结论符合以前的实验结果。
