The effect of laser irradiation (Ar laser, λ = 488 nm) on the atomic order and electronic structure of amorphous YBaCuO films is studied. It is shown that the laser irradiation of amorphous YBaCuO films leads to a sequence of processes having an oscillating character: energy accumulation (I incoh → max), accompanied by stronger atomic disordering, and relaxation (Jcoh → max) due to atomic ordering and a change in the predominant cluster configuration, (11l) - (10l), at incident powers above 2 W. This corresponds to a local topological ordering of the solid solution with the participation of copper-oxygen chains, accompanied by an increase in conductivity by two orders of magnitude.
