KTA Crystals
KTA is an excellent optical non-linear crystal developed recently for non-linear optical and electrooptical device applications.


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 sources of tunable laser radiation exhibiting energy conversion efficiencies above 50%. KTA has significantly lower absorption in 2,0-5,0 μm range compared with KTP nonlinear crystal. KTA crystal also diverges from other nonlinear crystals with its high damage threshold.
  • Large nonlinear optical and electro-optical coefficients
  • Low dielectric constants, loss tangent and ionic conductivities (much less than that of KTP)
  • High damage threshold
  • Wide angular bandwidth and small walk-off angle
  • Non-hygroscopic crystal
