For SHG of 1064nm, the standard coating is dual band AR (DBAR) at 1064nm/532nm with residual reflectivity <0.2% @ 1064nm and < 1.0% @ 532nm per face. HR@1064 and HT@532nm is available for compact laser-SHG devices.

KTP may suffer from optical damage known as "gray tracking". Maintaining KTP crystal at an elevated temperature ( e.g., 80oC) can help to reduce the formation of gray tracking. Please refer here for more information on the oven for heating up crystals.
