• Quality KTP crystal with high environmental resistance and long service life
HGTR (high anti-grey track) KTP crystal developed by hydrothermal method overcomes the common phenomenon of electrochromism of the flux-grown KTP, thus has many advantages such as high electrical resistivity, low insertion loss, low half-wave voltage, high laser damage threshold, and wide transmission band.
KTP Pockels cells made by HGTR-KTP crystal are mainly used in pulse lasers with narrow pulse width and high repetition frequency. Giving advantages of high extinction ratio, low half-wave voltage, and no piezoelectric ringing effect under high repetition frequency, KTP Pockels cells are widely used in laser ranging, laser lidar, medical lasers and industrial lasers, etc.
