KTA Nonlinear Crystal

KTA Nonlinear Crystal

Potassium Titanyl Arsenate (KTIOAsO4), or KTA, is a nonlinear optical crystal for Optical Parametric Oscillation (OPO) application. It has good nonlinear optical and electro-optical properties, e.g. significantly reduced absorption in band range of 2.0-5.0 um, broad angular and temperature bandwidth, low dielectric constants.

Key Features and Applications

  • Large nonlinear optical coefficient
  • Broad temperature and spectral bandwidth
  • High damage threshold
  • Can withstand higher power density
  • KTA crystals size upto 15x15x3 mm
  • AR and BBAR coatings for VIS-IR and mid IR ranges
  • Standard and customized mounts and housings
  • Technical consulting
