An exact calculation of the photodisintegration cross section of 3H, 3He, and 4He is performed by using as interaction the correlated Argonne V18 potential, constructed within the unitary correlation operator method (VUCOM). Calculations are carried out by using the Lorentz integral transform method in conjunction with a hyperspherical harmonics basis expansion. A comparison with other realistic potentials and with available experimental data is discussed. The VUCOM potential leads to a description of the cross section that is very similar to that of the Argonne V18 interaction with the inclusion of the Urbana IX three-body force for photon energies 45\ensuremath\leqslant\ensuremathω\ensuremath\leqslant120 MeV, whereas larger differences are found close to threshold.
