Technical Data

KTP (Potassium Titanyl Phosphate) is a nonlinear optical material generally used for frequency conversion of solid-state lasers, such as Nd:YAG.

KTP is widely recognized for these features:

  • Very high SHG coefficient: approximately three times higher than KDP
  • High Laser damage threshold
  • Highly environmentally stable- non hygroscopic, thermal, chemical and mechanically stable
  • Large aperture up to 50×50 mm
  • Variety of efficient applications- SHG, OPO, OPA, PPKTP
