KTA, titanium oxygen and potassium arsenate
KTA potassium titanium oxyarsenate KTiOAsO4 crystal is an excellent nonlinear material and one of the KTP crystals. Compared with KTP, KTA has a larger nonlinear optical coefficient, wider angle and temperature matching bandwidth; Capable of using Nd: YAG (1064nm) laser pumping to achieve non critical phase matching; It has lower conductivity and ion conductivity than KTP crystals, higher thermal conductivity, and does not produce thermal lensing effect during high-power laser pumping, making it suitable for high repetition frequency and high energy mid infrared output; The absorption loss of KTA in the spectral range from 3000 nm to 5000 nm is much lower than that of KTP crystals (solving the problem of the absorption peak of KTP crystals near 3.4 μ m), has high resistance to light damage and is widely used in optical parametric oscillators (OPO) in mid infrared.

Electro-optic deflectors (EODs) are optical devices used to steer or deflect light beams by applying an electric field to a specialized optical crystal. Unlike mechanical beam steering systems that rely on moving mirrors, electro-optic deflectors enable high-speed, non-mechanical beam control with exceptional precision and responsiveness. They are widely used in laser scanning, optical communications, microscopy, laser printing, spectroscopy, and scientific research, where rapid and accurate laser beam positioning is essential.
