Gray track is the induced absorption when irradiated with light having short wavelengths in the VIS or UV spectrum, and often leads to subsequent photochromic damage. Regular flux-grown KTP often suffers from gray track damage attributed to the polarons. The hydrothermal-grown HGTR KTP exhibits a much stronger gray track resistance in comparison to normal KTP (about 5X-10X the magnitude of KTP).
Shalom EO offers HGTR KTP crystals for electro-optical modulation applications. Besides the superior gray track, our HGTR KTP also boasts a high damage threshold (damage threshold: ≥2GW/cm2 @1064nm, TEM00,10ns,10Hz), excellent thermal/mechanical properties, great chemical stability, which makes them suitable for making electro-optic devices with outstanding overall performances.
