    "abstract": "The distorsion of a spontaneous downconvertion process caused by an auxiliary\nmode coupled to the idler wave is analyzed. In general, a strong coupling with\nthe auxiliary mode tends to hinder the downconversion in the nonlinear medium.\nOn the other hand, provided that the evolution is disturbed by the presence of\na phase mismatch, the coupling may increase the speed of downconversion. These\neffects are interpreted as being manifestations of quantum Zeno or anti-Zeno\neffects, respectively, and they are understood by using the dressed modes\npicture of the device. The possibility of using the coupling as a nontrivial\nphase--matching technique is pointed out.",
