Product overview

KTA or Potassium Titanyl Arsenate (KTiOAsO4) is an excellent nonlinear optical crystal for Optical Parametric Oscillation(OPO) application. It has better nonlinear optical and electro optical coefficients, significantly reduced absorption in the region of 2μm to 5μm, broad angular and temperature bandwidth, low dielectric constants.
