KTA or Potassium Titanyl Arsenate (KTiOAsO4) is an excellent nonlinear optical crystal for Optical Parametric Oscillation(OPO) application. It has better nonlinear optical and electro optical coefficients, significantly reduced absorption in the region of 2μm to 5μm, broad angular and temperature bandwidth, low dielectric constants.
Manufacturer and exporter of KTA Crystal ( Potassium Titanyl Arsenate Crystal / KTiOAsO4 crystal).
KTA Crystal Advantage:
- 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 and high transmission in the 3-4 µm spectrum range than KTP.
- Highly resistant to high intensity laser radiation.
KTA Crystal Application:
- An excellent NLO crystal developed mainly for Optical Parametric Oscillation (OPO)
- Frequency Doubling (SHG @1083nm-3789nm)
- Sum and Difference Frequency Generation (SFG)/(DFG)
- NCPM cut 1064—>1533+3475 (type I Theta=90deg., phi=0deg.)
