GTR-KTP
GTR-KTP crystals have gray track resistance sufficiently greater than typical flux grown KTP. This is possible due to advances in the controlled growth of KTP crystals, using proprietary modified fluxes and heat treatment. These GTR-KTP crystals are suitable for high power density applications, where regular flux-grown KTP crystals would suffer from gray track damage.
