title: Diffraction cancellation over multiple wavelengths in photorefractive dipolar glasses.
abstract: We report the simultaneous diffraction cancellation for beams of different wavelengths in out-of-equilibrium dipolar glass. The effect is supported by the photorefractive diffusive nonlinearity and scale-free optics, and can find application in imaging and microscopy.
