Gray track damage is a serious damage to which conventional flux-grown KTP crystal is susceptible, the hydrothermal-grown KTP has high damage threshold and high ability to anti gray track (damage threshold: ≥2GW/cm2 (@1064nm,TEM00,10ns,10Hz)), and furthermore it has a high resistivity, which makes it suitable for making electro-optic devices with excellent properties. Hangzhou Shalom EO provides a variety of HGTR KTP crystals used in the pockels cells.
