Potassium Titanyle Arsenate (KTA)

Catalog No. OP2200

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%. In addition KTA has a very high damage threshold and lower absorption in the 3-4 µm spectrum range than KTP.
