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.Scitlion is able to offer
Rod diameter from 1mm to 30mm
Length from 1mm to 30mm
