Introduction
CLaser 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
KTP is a positive biaxial crystal, with the principal axes X, Y, and Z (nz>ny>nx) parallel to the crystallographic axes a, b, and c, respectively.
