We demonstrate a method to compensate for the effect of the anisotropy in the spatial distribution of the radiation generated by parametric down-conversion (PDC) in bulk crystals. In order to achieve this task, a single nonlinear crystal is replaced by two consecutive crystals with opposite walk-off directions. We implement a simple numerical model to calculate the spatial distribution and correlations of PDC light in the low-gain regime, which takes the anisotropy of the crystals into account. Experimental results are presented which prove the validity of both the model and the method.
