Periodically poled crystals of KTP family: a review

Electronic structures and optoelectronic properties of ATiOPO4 (A = H, Li, Na, K, Rb, Cs, Fr, NH4, Ag) compounds and their applications in water splitting, CO2 reduction, and photo-degradation

“…They possess outstanding physical properties, such as high nonlinearity [1], wide range of transmission wavelengths [2], high absorption coefficient [3], excellent chemical and thermal stabilities [4], and ion exchange characteristics [5]. More than hundred compounds belong to KTP family [6][7][8], about ninety in which the potassium, titanium, and phosphorus atoms were replaced or doped by other elements. The chemical formula of this family is ATiOXO 4 , where A is K, Li, Na, K, Rb, Cs NH 4 , and Ag; and X is P or As.…”

“…The titanium atom is replaced by Nb, Zr, Hf, Ge, Sn, Sb, Ta, Fe, and Zn. The KTP family are generally synthesized by two methods: hydrothermal growth and flux growth [8]. These materials have piezoelectric and ferroelectric properties [9], and have high laser damage threshold [10].…”

Potassium titanyl phosphate (KTP) quasiparticle energies and optical response

“…Potassium titanyl phosphate (KTiOPO 4 , KTP)-a member of the ferroelectric MAOXO 4 crystal familypromises numerous technological applications due to its interesting optical properties [1][2][3][4][5][6]. Its large optical transparency range in conjunction with large electro-optical coefficients and nonlinear susceptibilities [7] are, e.g.…”

“…For example, they are all positive biaxial crystals (point group: mm2); they have a long transparency range (0.35 µm -3 µm), reasonable nonlinearity, reduced walk-off in the X-Y plane and a high optical damage threshold. All these crystals possess ferroelectric properties, and are suitable for use in periodically polled structures [25][26][27].…”
