ABSTRACT
In this paper we describe the progress in the study of scale-free optical
propagation when the cooling rate is above threshold value. In order to grasp the core
idea behind scale-free optics, paraxial ray scalar approximation, has been considered.
Diffraction-free (zero effective wavelength) solutions of equation(5) are scale free.
This effect has been found in the Gaussian exact solution for 2
