Potassium Titanyl Phosphate(KTP or KTiOPO4) is a nonlinear optical crystal, which possesses excellent nonlinear and electrooptic properties. Acombination of high nonlinear coefficient, wide transparency range, and broad angular as well as thermal acceptances makes KTP very attractive for different nonlinear optical andwavequide applications. Transparency band edges of KTP crystal are at 0.35 µm in UV and at 4.4 µm in IR region.Due to very high effective nonlinearity (d ~8.3 x d (KDP) at 1.06 µm) and excellent optical properties KTP perfectly suits as lasing material in various applications.
