GTR-KTP Crystal

GTR KTP

Introduction

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

Lasertec Inc develop the new GTR-KTP crystals. GTR-KTP has the following exceptional properties compare with the S-KTP:

High damage threshold

Without gary-track in high power cw intracavity application.

Lower absorption in 532nm

Higher resistivity

GTR KTP Applications:

Frequency doubling (SHG) of Nd-doped lasers for green laser..
