“…Potassium titanyl phosphate, KTiOPO (KTP), and its substantial family of isostructures have been of interest in recent years because of their exceptional nonlinear optical (NLO) and electrooptical properties (1)(2)(3), especially for the second harmonic generation (SHG) of 1.064-m Nd lasers (4). Many isostructural analogues have been synthesized by partial or full isomorphous substitution of K, Ti, P, and/or O, which constitute a structural field with more than 100 compounds (2,3,(5)(6)(7), and, therefore, this family of compounds now forms a particularly advantageous series for the investigation of the relationship between the crystal structure and its optical properties.…”

Potassium Titanyl Phosphate (KTiOPO,) is one of the best nonlinear optical crystals for the frequency doubling of 1.06 pm Nd:YAG lasers. Its large optical nonlinearity, high optical damage threshold and outstanding thermal stability has made it the material of choice for high power industrial and medical laser applications where reliability are of prime importance. Yet, KTP is just one member of the isomorphic compounds having the generic composition MTiOXO, where {A4 = NH,, K, Rb, TI and Cs} and {X = P and As}. Along with its isomorphs, KTP offers exceptional versatility for device design and optimization in both bulk-and micro-optical applications. This versatility is directly related to the open covalent crystal structure of KTP. In this paper, we review recent progress in the understanding of the crystal chemistry of the KTP family of isomorphs and summarize recent progress in KTP-based devices.

“…To date, potassiumtitanyl phosphate KTiOPO, (KTP) appears to be an attractive candidate for second harmonic generation (SHG) applications. This material exhibits a high nonlinear optical coefficient, a large temperature acceptance width, and a high damage threshold that make it well suited for high power SHG ofthe Nd: YAG laser radiation at 1.064 pm [I] to [3].…”

Polarization measurements as a function of temperature are performed on KTP monodomain single crystals, in both, insulating and conducting electrode arrangements. The low temperature study allows to determine the pyroelectric coefficient IK( = 2.97 nC ern-.' K -' which is constant over a wide temperature range. In the case where insulating electrodes are employed it is shown that bulk charge compensation of the spontaneous polarization field occurs around 148 K in the flux-grown samples.Polarisationsmessungen in Abhangigkeit von der Temperatur werden an KTP-Eindomanen-Einkristallen mit isolierenden sowie mit leitenden Elektrodenanordnungen durchgefuhrt. Die Untersuchung bei niedrigen Tcmperaturen ermoglicht den pyroelektrischen Koeffizienten In1 = 2,97 nC ern-' K ' zu bestimmen, der in einem weiten Temperaturbereich konstant ist. Fur den Fall, daB isolierende Elektroden verwendet werdcn, wird gezeigt, daIj die Volurnenladungskompensation des spontanen Polarisationsfeldes bei etwa 148 K in Proben, die mit der FluDwachstumsmethode hergestellt wurden, auftritt.
