Abstract

The Potassium Titanyl Phosphate, KTi0PO4 (KTP) is crystalline ferroelectric nonlinear material suitable for optoelectronics particularly for frequency doublers and waveguides. The symmetry change (mm2-mmm) at the high-temperatureferroelectric phase transition is such, that the crystal in the room-temperatureferroelectric phase is divided into the 180-degree domains with the collinear crystal lattices. For some practical usage, in particularly in the second harmonic generators the presence of domains is very undesirable because it radically reduces effectiveness of SHG . On the other hand, some other applications need regular domain structure. _
