2012年10月31日 · Nonlinear optics involves effects where the induced polarization in a medium does not linearly depend on the electric field of the light. This allows frequency conversion via processes like second harmonic generation and sum frequency generation.

2014年9月24日 · This document discusses nonlinear optics and summarizes key topics covered: - It describes the difference between linear and nonlinear optics, where linear optics involves weak light that is unchanged and nonlinear optics involves intense …

2014年8月20日 · 非线性光学（nonlinear optics, NLO）：是研究在强光作用下物质响应与场强之间的非线性关系的科学。 在强激光的作用下，材料的电极化强度P不再与入射光的场强E成简单的线性关系，而成幂级数关系： P = χ (1)E + χ (2)E·E + χ (3)E·E·E + … 其中χ (2)为二阶非线性极化率 ，对应着二阶非线性光学效应。 NLO聚合物材料 NLO聚合物材料具有明显高于无机晶体的非线性系数、皮秒至飞秒的响应速度、很高的光学损伤阈值，尤其是它的分子可修饰性、高分子可加 …
