Using the history dependence of a dipolar glass hosted in a compositionally disordered lithium-enriched potassium tantalate niobate (KTN:Li) crystal, we demonstrate scale-free optical propagation at tunable temperatures. The operating equilibration temperature is determined by previous crystal spiralling in the temperature/cooling-rate phase space.

  7. The model breaks down for scales at which the space charge saturates. This is a sample-dependent limit associated with the acceptor density NA and the static εr. In typical KTN:Li samples, NA≃2·1018  cm−3, so that even in the critical regime with εr∼105, the model breaks down for beam widths l∼0.1  μm.
