Optical nonuniformities observed in second-harmonic generation experiments on large KTiOPO4 crystals (dark line defects) are shown to be directly related to the presence of complex domain walls. It is unlikely that these domains are ferroelectric; however, their polar nature suggests they may be similar to the Dauphiné twins observed in quartz.
