研究目的
Investigating the phenomena that occur as a consequence of the modification of the optical properties of a material system by the presence of light, focusing on second-harmonic generation and other nonlinear optical effects.
研究成果
The study confirms that nonlinear optical phenomena, such as second-harmonic generation, are a direct consequence of the nonlinear response of materials to intense optical fields. These findings emphasize the importance of material properties and light intensity in nonlinear optics and suggest future studies on materials with higher nonlinear susceptibilities and more efficient detection methods.
