In fact \psi(z) defined in the latter equation is subtracted from phase as shown in a former equation in the same article.undo

The reference (doi:10.1103/physreva.45.8185) given does not actually give the normalization constant (see Eq. (5)) therein, but leaves it undetermined. The new reference (https://doi.org/10.1364/OL.40.001717) explicitly gives the correct normalization constant.undo
