We demonstrate simultaneous diffraction cancellation for multiple light wavelengths in dynamic dipolar glass. This finding, driven by photorefractive nonlinearity, advances optical imaging and microscopy techniques.
Area of Science:
- Nonlinear Optics
- Condensed Matter Physics
- Photorefractive Materials
Background:
- Dipolar glasses exhibit complex dynamics under non-equilibrium conditions.
