• Introduction: 

Potassium Titanyl Arsenate (KTiOAsO₄), or KTA crystal, is an excellent nonlinear optical crystal for Optical Parametric Oscillation (OPO) application. It has better non-linear optical and electro-optical coefficients, significantly reduced absorption in the 2.0-5.0 µm region, broad angular and temperature bandwidth, and low dielectric constants. And its low ionic conductivities result in a higher damage threshold compared with KTP .

• Optical Properties：

1) High damage threshold

2) Broad temperature and spectral bandwidth

3) Highly resistant to high-intensity laser radiation.

4) Wide angular bandwidth and small walk-off angle

5) Large nonlinear optical and electro-optical coefficients

6) Lower absorption in the 3-4 µm spectrum range than KTP.

7) Low dielectric constants, loss tangent and ionic conductivities (much less than that of KTP)
