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 Crystal has significantly lower absorption in 2,0-5,0 μm range compared with KTP nonlinear crystal. KTA Crystal crystal also diverges from other nonlinear crystals with its high damage threshold.

KTA crystal features large non-linear optical and electro-optical coefficients in comparison to KTP and has the added benefit of significantly reduced absorption in the 2 to 5 µm region.  It has found wide applications in second harmonic generation (SHG), sum and difference frequency generation (SFG)/(DFG), optical parametric oscillation/ amplification (OPO/OPA), and electro-optical Q-switching involving MIR wavelengths.

Crystals of KTA are important for second harmonic generation (SHG), sum and difference frequency generation (SFG)/(DFG), optical parametric oscillation (OPO), electrooptical Q-switching and modulation and as substrates for optical waveguides. OPO devices based on these crystals are reliable, solid state sources of tunable laser radiation exhibiting energy conversion efficiencies above 50%. KTA has a very high damage threshold. No optical damage was observed at the levels of 10 – 20 GW/cm2 with the picosecond dye laser. This crystal is grown using high temperature flux technique.

Nonlinear KTA crystals for OPO applications:

• Optical parametric oscilator in middle IR region 1 – 5.5mkm
• Different frequency generator in middle IR region 1 – 5.5mkm.
