KTP Crystal
KTP (Potassium Titanyl Phosphate, KTiOPO)
is Raicol’s first crystal with over 25 years of experience. Our growing and fabrication processes have been optimized to produce the highest quality crystals. Raicol offers dedicated crystals for different applications offering highly efficient KTP and relatively high LIDT. KTP is a nonlinear optical material that is widely used for doubling solid-state lasers, such as Nd:YAG. KTP’s nonlinear coefficients makes it the leading material for SHG in the optic industry. KTP is recognized for highly efficient OPO, SHG & Quantum applications.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
