OEM/ODM Manufacturer Mgo:Linbo3 - KTA Crystal – WISOPTIC Detail:
KTA (Potassium Titanyle Arsenate, KTiOAsO4 ) is a nonlinear optical crystal similar to KTP in which atom P is replaced by As. It has good non-linear optical and electro-optical properties, e.g. significantly reduced absorption in band range of 2.0-5.0 µm, broad angular and temperature bandwidth, low dielectric constants.
Compared with KTP, the main advantages of KTA include: higher second-order nonlinear coefficient, longer IR cut-off wavelength, and less absorption at 3.5 µm. KTA also has lower ionic conductivity than that of KTP, which results in a higher laser induced damage threshold.
KTA is very popularly used for Optical Parametric Oscillation (OPO) application which gives high energy conversion efficiency (above 50%) of tunable laser radiation in solid lasers.
