KTiOAsO4 (KTA Potassium titanyl arsenate) – Laser Crystal – Nonlinear Crystal – Customized Products

KTiOAsO4 (Potassium Arsenate Titanium Oxide) crystal is an excellent nonlinear material, one of the KTP crystals, compared with KTP, KTA has a larger nonlinear optical coefficient, wider angle and temperature matching bandwidth; can be pumped with Nd: YAG (1064 nm) laser, can achieve non-critical phase matching; has lower electrical conductivity and ionic conductivity than KTP crystal The high thermal conductivity of KTA is suitable for high frequency and high energy mid-infrared output because it does not produce thermal lensing effect during high power laser pumping; the absorption loss of KTA in the spectral range of 3000 nm~5000 nm is much lower than that of KTP crystal. The absorption loss of KTA is much lower than that of KTP crystal in the spectral range from 3000 nm to 5000 nm (solving the absorption peak problem of KTP crystal near 3.4 μm), and has a relatively high resistance to optical damage, which is widely used in optical parametric oscillators (OPO) in the mid-infrared.
