We study experimentally the aging of optical spatial solitons in a dipolar glass hosted by nanodisordered sample photorefractive potassium-sodium-tantalate-niobate (KNTN). As system ages, waves erratically explore varying strengths nonlinear response, causing them to break up and scatter. show that this process can still lead solitons, but generalized form for which changing response is compensated normalized wave size intensity so as maintain fixed waveform.
