THE 2-MINUTE RULE FOR BIBO CRYSTAL

Hygroscopic crystal products deteriorate when they are not often held in adequately dry air (or a dry purge gas). This is applicable e.g. to KDP and BBO, As well as in a lesser extent to LBO. It may be useful to help keep this kind of crystal in a somewhat elevated temperature, which makes it much easier to keep it dry.Laser processing and material
