KTA Crystal

Potassium Titanyle Arsenate (KTiOAsO4, or KTA) crystal is an excellent nonlinear optical crystal for Optical Parametric Oscillation (OPO) Application. OPO devices based on KTAs are reliable, solid state, tunable laser radiation exhibiting energy conversion efficiencies above 50%. In addition, KTA has a very high damage threshold.
Advantages:
  • Large nonlinear optical and electro-optical coefficients
  • Wide angular bandwidth and small walk-off angle
  • Broad temperature and spectral bandwidth
  • Low dielectric constants, loss tangent and ionic conductivities (much less than that of KTP)
  • High damage threshold
  • Lower absorption in the 3-4 µm spectrum range than KTP
  • Highly resistant to high intensity laser radiation.
