Nonlinear optical Potassium Titanyle Arsenate crystal KTA

Potassium Titanyle 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, low dielectric constants. And its low ionic conductivities, Lower absorption in the 3-4 μm spectrum range result in higher damage threshold compared with KTP Crystals.

Nonlinear Optical Crystal KTA crystal has highly resistant to high intensity laser radiation, and the application of NLO Crystals KTA Crystals is including Frequency doubling (SHG @ 1083nm-3789nm), Sum and Difference Frequency Generation ( SFG ) / ( DFG ) , Electro-Optical Q-switch and modulation for Optical waveguides Frequency Doubling (SHG) of Nd-doped Lasers for Green/Red Output, Parametric Sources (OPG, OPA and OPO) for 0.6mm-4.5mm Tunable Output.
