Non-linear effect

Manukumara Manjappa | TeraQuaNTA Lab

"Non-linear effects occur when the output of a system is not directly proportional to its input. The demonstration will showcase how materials respond differently to strong stimuli compared to weak ones. For example, it could involve shining a high-intensity laser through a crystal and observing the generation of light at different frequencies (like second harmonic generation). This will visually explain how the material's properties change under intense fields, leading to effects like frequency doubling or tripling. This is fundamental in areas like photonics, materials science, and even biology."
