Lines of various forms of stimulated scattering have been revealed in the scattering spectrum excited by pulsed second-harmonic radiation of a YAG:Nd³⁺ laser in an initially homogeneous aqueous colloidal solution (suspension) of polystyrene nanoballs. Dynamic light scattering measurements have shown that the laser-stimulated coagulation of some nanoballs with the formation of particles with an order-of-magnitude larger size occurs in the solution. An explanation of this phenomenon has been proposed.

激光辐照下物理化学性质发生变化的胶体溶液受激散射特征

在最初均匀的聚苯乙烯纳米球胶体水溶液（悬浮液）中，由 YAG:Nd ³⁺激光的脉冲二次谐波辐射激发的散射光谱中揭示了各种形式的受激散射线。动态光散射测量表明，在溶液中发生了一些纳米球的激光刺激凝结，并形成了一个数量级更大尺寸的粒子。已经提出了对这种现象的解释。
