KTA crystal

KTA crystal

KTA (Potassium Titanyl Arsenate) has very similar features to KTP but adds the benefit of a good optical transmission between 3µm and 3.5µm:

  • Transparent between 0.5µm and 3.5µm
  • High non-linear optical efficiency
  • Large temperature acceptance
  • Lower birefringence than KTP resulting in a smaller walk-off

 

It is often used as an OPO / OPA gain medium for emission in the 3µm range as well as an OPO crystal for eye-safe emission at high average power.

What makes us different:

  • Excellent optical and non-linear optical homogeneity
  • High damage threshold of AR-coatings: >10J/cm² at 1064nm for 10ns pulses
  • AR-Coatings with low absorption at 3µm available
  • Qualified for space projects
