Nonlinear Photomechanics

Nonlinear optics is based on light-induced changes the optical properties of material. In analogy, nonlinear photomechanics deals with the phenomena of light-induced changes of a material's mechanical properties. Combining nonlinear optics with nonlinear mechanics can lead to super-intelligent morphing materials.

Making Samples

Getting good experimental results requires making good samples. Here are the nuts and bolts of sample preparation.

Thin Films

Making a high optical quality thin film sample requires a clean substrate. A voltage can be applied to a sample using glass substrates that are coated with transparent Indium Tin Oxide (ITO) as an electrode.
