Description
KTA (Potassium Titanyle Arsenate – KTiOAsO4) is an excellent optical non-linear crystal mainly developed for Optical Parametric Oscillation(OPO).
OPO devices based on KTAs are reliable, solid state sources of tuneable laser radiation exhibiting energy conversion efficiencies above 50%. In addition KTA has a very high damage threshold.
While being comparable to KTP in terms of non-linear efficiency and ease of use, the main advantage of KTA material over KTP lies in its significantly reduced absorption in the 3-4 µm range.
