Product Description

KTP Crystal Potassium Titanium Oxide Phosphate (KTiOPO4 ) Crystal


The main advantages of KTP crystals are:

*Large nonlinear optical coefficient

*Large receiving angle, small departure angle

*Wide temperature and spectral bandwidth

*High photoelectric coefficient and low dielectric constant

*High impedance ratio

*Non absorbent, chemical and mechanical stability
