GTR-KTP - Gray-Track Resistance KTP

KTP is an excellent nonlinear crystal, but its gray tracking phenomena limits its use in high repetition rate and high power laser systems.  GTR-KTP crystal has higher gray tracking resistance than the regular flux grown KTP crystal. Through Photo-thermal Common-path Interferometer, the occurrence of gray tracking can be measured by an increase of bulk absorption through a strong CW 532 nm green laser within several minutes.

Apparently Hundreds optics's GTR-KTP has lower absorption than the conventional KTP in the range of 350-550 nm. We can conclude that Hundreds optics 's GTR-KTP is expected to have a higher gray tracking resistance than the regular flux grown KTP crystals.
